Warlocks of course having no proficiency with shields by default... Also you entirely left out the impact of feats so far as I can tell - and those have changed a lot. So basically you're comparing the new warlock to the 2014 fighter. And it's unclear what you've done with the fighter's third feat.
Sigh, well, it was too much to hope for we could discuss the numbers I had instead of immediately saying I did it wrong. Fine, let's talk about feats.
Also, if we want to insist on pointing out the Warlock can't
really sword and baord, then there is no issue in upping all their damage dice to d10's
For the record a level 5 One D&D fighter, barbarian, or paladin should have a Str of 18 and a damage bonus from something like Charger or Great Weapon Master.
Wrong. At least, wrong unless you start with two odd scores.
The only way you are getting 18 strength and a feat is if you decide to start level 1 at 17 strength, meaning your secondary score is 15. So, if a fighter wants 18 strength, they need to accept a 15 Con, reducing their overall hitpoints and survivability. Not that you can't make that trade, it just isn't a trade I think every single character is going to make every single time.
Also, Greatweapon Master doesn't work with Sword and Board. In fact, of the new feats, the only straight damage increase Sword and Board can get is Charger. Which requires moving 10 ft towards your target, and gives you +1d8 on that single attack you make afterwards. I can include it if you want, but that is quite literally a difference of ~3 points on a single turn, and only activates again if they can move again.
You will note the numbers at level 11 (the problem level) have the Bladelock without hex or Eldrtich smite ahead of the fighter by 3 points, ahead of the barbarian by 2 points, and ahead of the paladin by 5 points. And this is before I switch the Bladelock to 1d10 damage dice, for using the weapon two-handed. Meaning it looks like even with Charger added.. the Bladelock will come out ahead.
So, how about this. Instead of me trying to guess what you want, give me your best fighter build, your best paladin build, and your best barbarian build, and I'll see if I can make a Bladelock that surprasses them at level 11. Be warned though, if you pick a subclass, then I will pick a subclass.
Add that in to the mix and things change. A level 11 fighter should have a Str of 20 and three feats. Meanwhile a warlock's only combat feat that adds to Cha is War Caster.
And who needs combat feats when you are already beating everyone in martial damage? Especially when taking something like Warcaster is BRUTAL on the Bladelock.
Yes, if you miss fairly significant changes and class features off one side of the equation that the other can't take in the name of "simplicity" you get odd results. (This of course is another OneD&D change; the Chaladin is probably viable but due to feats they aren't the monster they are in 2014 D&D)
Strawman and false. I didn't miss anything. I knew there was a single feat for the fighter I wasn't accounting for, and I knew that Sword and Board characters didn't have combat feats to increase their damage by a significant degree. And I NERFED the Bladelock damage by keeping with the one-handed weapon instead of two-handed in the entire example.
