"This game shouldn't have that. It's unncessary."

[RJ 17]

When people say that something is unnecessary in the game it's usually to point out redundant systems/mechanics...or systems/mechanics that serve absolutely no purpose to the core gameplay. Luckily: such things can easily be ignored.

That said, though, Tracer in Heroes of the Storm is certainly and completely unnecessary. :3

I would say that what isn't necessary are all the things that get in the way of the fun. Anything requiring always-on BS, for one. I mean, some people like multi-player, but that's suppose to be optional, yo.
