The entire point of playing ranged is having the ability to avoid getting hit. If ranged characters are forced to take mandatory damage that hits harder than anything else in the game, there is absolutely no point in playing ranged. Instead just play melee and do the same DPS AND be tankier.
Exactly. Ranged classes are by nature 'glass cannons', it's the whole point of the class, hell one of the ranged classes in this game even has a skill called Glass Cannon. It would make precisely zero sense for a game developer to promote glass cannon builds only to make them suffer the most from the hardest hitting thing in the game.
This arguement is not fair to any classes.
If your arguement should be the fact, why would anyone roll melee?
RD is not hitting you any harder than it should.
It's doing it's job as it is.
Barbs, monks and melee wizards are not designed to be tanks.
They can't hold aggro.
If ranged is not expected to take damage, then go play WoW where there are proper tanks and healers.
THIS GAME IS NOT WoW!!!
Oh! I forgot! Even in WoW, ranged still take damage!!!
This game, in a sense, has been designed for you to die one way or the other.
Our purpose is to find a way to survive it.
