Complete waste of Blizzard's time.

If a PC Gamer wants controller support there are a lot of choices to make this happen so no need for a Dev to waste time doing this.

Look into Pinnacle game profiler. I tried xpadder. But xpadder is very limited. Game profiler allows for very complex mappings(detecting button hold, key stepping/sequencing, shift mapping and some more). And great thing is people already made profiles for a lot of games, so you don't have to do the mapping yourself.

It works well enough on console but I still missed pinpoint accuracy especially for ranged abilities. Not being able to cast on particular mobs to be most effective wasn't game breaking though but playing a Wizard got dumbed down somewhat (more so than other classes I think).

I still had fun though so was worth it to me. I think monk/barb got best benefit out of controllers by far.

What D3 really did for me was remind me how long since we got a good beat'em up/top down action RPG on consoles. I missed all of the BG/Xmen//EQ/etc as M:UA games were practically all we got that were definitely worth the purchase. I plan on picking up Marvel Legos on PS4 as seems best I can get (Lego games to be fair are cool but decidedly more family friendly and less "serious").

I actually hate the way mouse control is implemented in the game, I'd swap for properly designed and integrated pad controls in a heartbeat and maybe even play the game a little.
