Expansion has been fun until ability overload has made me lose almost all interest

[Quixotica]

No one would play this game 10 years later if we didn't get any new skills though.
More skills = More fun!
You will have plenty of time to cope.

More does not mean better, that is about as blatant a fallacy as you can get. DOTA restricts it's heroes to only a handful of abilities yet that game demands hundreds upon hundreds of hours played to even be a half decent player, simply because there is a lot of nuance and depth to those handful of abilities and a lot to learn about their use.

Cramming a bar full of abilities means nothing when half of them are superfluous or could be combined into more interesting things. Unless, I guess, all you care about is having 50 different flashy yet ultimately pointless animations to play.

I spent 7 years maining a class in WoW that is, to this day, notorious for ability bloat. I'm used to it. What the Dragoons have is peanuts in comparison. Though I'm having to arrange my 4 hotbars again, it's something I'm accustomed to.

I did too, more or less, just because we might be used to it does not mean it's good design.
