Why is the healer class basically a one spell dps class?

[Lyth]

'Utility' in this game historically translated into one of three things:
1) Resource generation
2) Reduce incoming damage
3) Increase outgoing damage

Players always prefer things that directly boost their dps. AST and cards are the obvious example. That doesn't mean that these are the only forms of utility that exist.

But here are the problems. This game is built on potato framework. The fact that the solution to the 'spin to win' bug was to animation lock all boss movements shows you how little control over fights that they can allow you before things start falling apart. And the instant that you give the playerbase anything with niche, situational ability, people start complaining that it can't be used under all conditions to min-max dps.

You want impact? Play dps.
