Considering that the fighter is wearing solid steel and carrying around a ginormous dinner plate in one hand, while the wizard is wearing pajamas...I'd think this would be the standard NON-metagaming assumption to start with...?![]()
Whoever is is back is easier to hit is a reasonable assumption. Even animals make it a point to move the softer squishier young behind the more durable adults.
Challenged enemies do know that they are both penalized for attacking squishies and the Fighter gets a free swing if they try
He will have, at level 12 assuming a +3(Githzeri) Plate an AC of 10[base]+6[lvl]+8[plate]+2[gith]+3[enh]+1[spec]+1[pit fighter]+2[shield]= 33 AC.
Now lets take a level 12 Wizard, 20+3 int, wand. He has an AC of 10[base]+6[lvl]+6[int]+3[enh]+1[special cloth]= 26
So if an enemy decides to attack the wizard as opposed to the fighter, he will take in an average of 8.2 damage each time he does so and his DPR increases by 5 damage per round.
The fighter using surges or not has little to no bearing on how much the leader heals: leader heals are restricted per encounter. The daily resource here is surges (with some powers being notable exceptions). If the fighter is ending on 8 surges while the rest of the party is on 0 to 2, then assuming each extra surge worth of damage he takes is equivalent to removing a surge worth of damage from another character (which isn't true: defender surges tend to be larger than those of others), the party could have gone another encounter before running out.This does not need to occur. The Fighter could have 8 surges left over and the rest of the party can have 0 to 2 surges left over and it could still be good. There is no way that a party can balanced this out completely, so it makes sense to have the PC attacked the most be the most heavily defended. If the Fighter never or rarely uses a surge in a given day, it just means that the Leader can spread his healing across 4 party members instead of 5. That's actually a good thing.
If foes ignore the Fighter, they will take a beating.
Also, even if the Fighter has an AC of 6 higher than the Wizard (unusual in the game, but it could happen), the DM would have to metagame the foes to have them take a swing from the Fighter in order to take a 4 better swing on the Wizard.
How does a foe KNOW that the Fighter has AC 3 higher than the Wizard without the DM metagaming the info?
A Fighter is not a Striker. Having a decent attack is good enough. It's not as if that's difficult with little effort.
Personally we and our DMs reveal defenses when you attack them. It just makes the game flow that much quicker.Wizards jump out of the way of attacks nearly as easily as those tanking Fighters glance an attack off of their armor. That's the physics of the game world.
So, NPCs should think that Wizards are not necessarily much easier to hit. Unless of course the DM is metagaming the exact numbers.
Usually it comes pretty close, but a good deal depends on how hard the fighter actually hits.The point is, is it worth a -2 to attack the squishier targets when there is also a fair chance that the Fighter is also going to get a free hit on you?
The wizard has ~68 hitpoints. The fighter has ~133 hitpoints. That carries over to how much they heal when they spend surges. All that adds up to mean that every point of damage that the foe does to the wizard effectively counts for twice as much as if he'd done it to the fighter, because it comes that much closer to downing a foe, and uses up that much more in terms of healing.
So, the monsters DPR adds 5 and then effectively doubles. That's a lot more than the 8.2 damage that he's taking back.
Only if they've observed the fighter before. The fighters mark is just a plain old mark. His combat challenge ability is a separate immediate interrupt ability that is not part of his mark. Its not until he uses it on someone [they then know the details of the CC attack] that they understand the extra consequences of ignoring a fighters mark. Not to be confused with the paladin's special mark which lets the enemies know.
Initially, marked enemies are only aware of the mark and not that they're going to get beat on for ignoring it.
Every time you attack an enemy, whether the attack hits or misses, you can choose to mark that target. The mark lasts until the end of your next turn. While a target is marked, it takes a –2 penalty to attack rolls for any attack that doesn’t include you as a target. A creature can be subject to only one mark at a time. A new mark supersedes a mark that was already in place. In addition, whenever a marked enemy that is adjacent to you shifts or makes an attack that does not include you, you can make a melee basic attack against that enemy as an immediate interrupt.
Whenever you affect a creature with a power, that creature knows exactly what you’ve done to it and what conditions you’ve imposed. For example, when a paladin uses divine challenge against an enemy, the enemy knows that it has been marked and that it will therefore take a penalty to attack rolls and some damage if it attacks anyone aside from the paladin.
Your second interpretation would make sense if fighters were not able to use combat challenge on marks they do not create[that still belong to them, ala bards "misdirected mark" at will] and on marks that are created by other powers.
fake edit: also, if you have access to the compendium, the Combat Challenge is clearly listed as a separate power[at will, immediate interrupt, with an effect of "Effect: Whenever an enemy marked by you is adjacent to you and shifts or makes an attack that does not include you, you can make a melee basic attack against that enemy."]
For fighters, its very clear they do not know until you hit them with it
