Saying your experience differs is a vastly different thing than saying his experience is "not true".
I share his experience as well. Our rogue ROUTINELY does more damage than both the fighters and the ranger in our group. AND he's the most skillful in our group, AND he speaks every regular language in the book, and he can never be hit it seems because he can full move, shoot his bow, and full move back behind cover. The rogue is scary powerful in our group, based on the last playtest. Sorry your experience differs, but your experience is not universal in this.
This is true, but WOTC has said that in their mind Fighters should be the BEST fighters. They do combat, it's their thing. No one should do more damage than them. No one should equal their damage.I'm not trying to be difficult here Mistwell - but it's not experience, it's math. A Rogue built and played with the same level of skill as a damage-oriented Fighter (which is the default in 5E) is going to do less damage than that Fighter, and be less survivable than the Fighter, and have less "clutch" power than the Fighter, as of the October playtest rules. That was not the case as of the September rules, where the Rogue would be less survivable, and have less "clutch", but routinely do equal or sometimes more damage.

So, if they want that design goal to be true, Rogues have to do almost as much damage.
I'd argue that the best fighters mean being the best at offense AND defense. Besides, in D&D more damage=always better. Damage is king and all that. When most battles end in one or two rounds and 1 point of damage can make the difference between someone in the group taking 20 points of damage or not(because the enemy dies and doesn't do an attack next round), then damage really in the most important thing.A reasonable post but unfortunately all founded on a bad or at least completely arbitrary and unsupported assumption - that being the best Fighter absolutely means doing the most damage. I would very strongly argue that being the best fighter means having a combination of damage, control and survivability. In 4E, Fighters were, really, the best at fighting, despite Rogues doing superior damage. In 5E, they could do less damage than Rogues, but out-do them in survivability, control and clutch (and they do!), and still be "the best fighters".
I guess huge is a matter of opinion. The final balance pass was after the last playtest so it's possible that the numbers are closer. However, even if they aren't, doing 70% of fighter's damage is pretty close. Not only that but given the fighter is making 4 attack rolls to get that damage the chance that he gets less than 100% is much higher than the Rogue. I'm not sure how to do the exact calculation but it's likely that the Rogue does more than 70% of the fighter's damage because of this.Also, 15 damage/round is huge - Rogues by your calculations only do 68.5% of the damage of a Fighter. That's barely 2/3rds. That's not even the same ballpark.

I guess when I'm used to the difference in 3e being nearly 100 points between the weakest and strongest person in the party, 15 points seems small and insignificant by comparison. The difference was much bigger than 15 points for most characters in 4e as well.
It has not been our experience in the game so far that the Rogue has felt anything but powerful. They do more damage by far on an average round than the Cleric or Wizard.
The average combat for us generally goes like this at 5th level:
Fighter hits one of his two attacks and does 14 damage
Wizard uses a cantrip and the enemy makes his save
Cleric uses a cantrip and the enemy fails its save doing 9 damage
Rogue hits doing 13 points of damage
The enemy goes, the fighter is already in melee and did the most damage so they attack the fighter. The fighter takes 20 damage and the round starts over.
Pet peeve of mine: Can we not use 20th level as a benchmark? Hardly anybody plays characters at that level, so it's a terrible guide to what the typical campaign looks like. And the relative damage output of fighters and rogues doesn't stay constant over the level range, it bounces around as different class abilities come online.
I just did some number-crunching to figure the damage output of a greatsword fighter (warrior path, great weapon style) and a dual short sword rogue across the whole level range. Here's how rogue damage stacks up to fighter damage, ignoring their respective "spike" abilities (Assassinate and Action Surge):
Level 1: +30%
Level 2: +30%
Level 3: +23%
Level 4: +18%
Level 5: -25%
Level 6: -32%
Level 7: -31%
Level 8-10: -17%
Level 11-13: -35%
Level 14-16: -26%
Level 17-19: -16%
Level 20: -30%
The rogue's big early advantage is due to the combination of dual wielding and sneak attack. From level 5 onward, you can see that the dominating mechanics are the fighter's multiple attacks and the rogue's sneak attack dice. The fighter gets an extra attack and surges ahead; the rogue's accumulating sneak attack dice erode that advantage bit by bit; then the fighter gets another attack and surges again. (One more reason level 20 is a bad benchmark: It's one of the levels where the fighter has just gotten another attack.)
Averaging across the first ten levels, which I would say is the best benchmark for a "typical" campaign, the rogue is dealing 87% of fighter damage. The average across all twenty is 78%, still respectable.
I suspect the fighter will do better when comparing archery skills... working on that.
I'm not trying to be difficult here Mistwell - but it's not experience, it's math.
Experience will vary it wildly, but the rules will remain the same.
People who are saying that their Rogue does as much damage or more than the Fighter as basically telling us that either the Fighter in their group is not built/played as well as the Rogue, or, I think, selectively remembering the Rogue's "big numbers" and not recalling the Fighter's multiple attacks and so on.
EDIT - This will be less of an issue at low levels, but at higher levels, once the Fighter gets his multiple attacks and so on...
EDIT - Surprise round addenda - Because the gap is so big, and Death Strike can be saved against, I kind of suspect that our two archers do pretty comparable damage even the Rogue is supposedly in his element. I haven't done the math on this yet, though.
