To make this game more balanced and less time consuming (no more “waiting for a tank”), Blizzard should think about (for the next expac) how to remove tank specs from the game and instead replace them with a “tank role” option. So no more Guardian druids, Protection warriors, Vengeance DHs etc. No more crying about how Tanks are OP, how to fix them in PvP etc.
Tank role should be an option available for ALL melee specs. You can activate it by selecting a tank role instead of dps role when queueing for a pve isntance. It would be available for PVE INSTANCES ONLY: for raids and dungeons. Not for PvP nor for open world.
And what do i mean with a tank role option?
Well, when you chose a tank role as a melee, you will get some mandatory, mostly passive, tank abilities.
Lets say you are an Assassination Rogue (a great spec for tanking, right:P) and you want to queue as a tank. You simply select a tank option instead of dps option. After you get teleported into dungeon or raid, you will passively get 150% more health, 300% more armor, 20% Leech or Versatility, more Dodge and/or Parry and almost 100% aggro uptime but all of your damaging spells/abilities will do roughly 30% - 40% less damage. Three or four of your CD abilities will be replaced by “tanking kind of abilities” For Example: Vanish could give you 50% dmg reduction for 10 seconds instead of Stealth, Sprint could be replaced by strong self heal, Poisoned knife could be replaced by Taunt on a short CD etc.
Warning: again, that would only work in instanced pve, if you chose a tank role as melee spec. As soon as you leave an pve instance group, you will be “transformed” back to your normal role.
If you wanna tank as Arms Warrior or Frost DK you will get slightly less bonus Armor, Leech and Stamina than Rogue i guess …
Does that mean that some classes would lose one of their specs? Yes and no. Less specs means more balance. Druid doesn’t need four specs at all.
Warrior Paladin, Monk and DK don’t need three specs, but i don’t mind replacing their tank spec with another dps spec if there is a will.
Demon Hunter is another story, because we can’t left it with one spec only, so in that case Blizzard should replace Vengeance tank with Vengeance dps (maybe more ranged oriented dps spec than Havoc?).
Some classes and specs are naturally better at tanking than others. For example: a Feral Bear or Frost DK are way better than Subtlety Rogue or WW monk. More squishy specs would simply be provided by more Armor, Health, Dodge/Parry and Leech than tougher specs, maybe some stronger defensive CDs should be added to them as well.
Edit: in Guild Wars 2 there are no tank specs, but you can keep aggro from a boss by simply equipping a gear with more armor and toughness. More armor you get more likely you will get focused by a boss.
