Having the best passive self-healing is why SK are so powerful and popular to play. For warrior, I think the balance point is simple. Warrior needs to be able have similar HP and DPS as a single, group game, blue-con NPC they might encounter. What I mean is that a level 50 warrior in defiant gear can defeat a single blue con NPC solo. They will have enough DPS to kill the mob before their own HP reaches zero, without any outside help or consumable potions. A level 115 warrior should be able to do the same thing, using their own abilities. It can be a close fight, but it should be winnable. What does that fight look like at level 115 for a warrior? Consider a 100k base DPS mob with 5M HP. A duel-wielding warrior does say 200k DPS, so that warrior needs a virtual HP pool of say 2.51M HP to win that fight. A warrior can mitigate the mob down to <65K DPS for 3 minutes, and chain/stack other mitigations with various limits. Since the answer to the next 2 questions is "No", a warrior now needs to mitigate/avoid enough damage to win in 1/4 of the time. Unless we want a 500k HP warrior sustaining 800K dps vs a typical mob, then they need a lot more toughness. Can a warrior boost their HP pool to anywhere near apx 2.51M HP? For the duration of the fight? No. Can a warrior passively heal anywhere near 100K HP/sec? With HP regen, heal procs, and activated abilities? No. Meanwhile, a knight can answer all 3 of those survival questions with a qualified "Yes". As proof that the warrior class is out of balance, I offer the hyper healing cleric class that is so 1-dimensional they cannot accomplish anything on their own either.
