Warden tanks can use also steal heal, they can also use a lot of autoattack stat and can heal with vamp / block / aggro, so what's the point? Barbarians can use stealheal, yes, but need to know this, most of Sentinnels classes uses skills as a buff, even the Legion side usses skills as a debuffers, Check templars, can heal stunning, paladins can heal with skills, blade dancer 1 clic and autoattack = heal, even Legion: Death Knight= can combo heal or vamp, barbarian skill heal or vamp, rogue skill heal with COMBO and with DEBUFF (same as seeker, but seeker survavility is with skills buff even rogues survavility is with debuff skills), and there are a lot of more examples, but this isn't the point, I just think barbarian should get another skill heal, because if u say that can heal with vamp, is ok, you're not wrong, have good damage, but if stun? Rip, have a resist skill yes!, in tank mode people keep it at 1/4 (4seconds) with cd of around 25/30 seconds, wardens can use resist but don't use vamp, so is a quite useless having resist for survavility because they have a passive, that makes any block heals him a percent of hp, and look at this, PERCENT, (Most of Sentinnels use heal skill depending on their maximum hp (beastmaster, seeker, paladin, druid, warden, TEMPLAR, mage, etc. Even Legion side most depends on damage as base or nothing as a base) and can heal their hp with aggro too, using percent of hp, why 2 heals if already so op tank, so I can understand that u say:
If a tank have dmg skill + resist skill = no need 2 heal skill.
Comparation:
Warden: Block Master (Healing skill) + Aggression (Healing Skill) + Resistance (Survavility skill) + {Skill that decreases enemy damage and increases a lot of autoattack stat} (Damage skill)
Barbarian: Combat Fury (Healing skill) + Resistance (Survavility skill) + Berserker Power (Damage skill)
If u think that the barbarian is already op then why warden better? If it's counter
And having resistance doesn't significate that makes x2 or x3 more damage
