So this has been a long standing issue with gamepad support that happened SEVERAL patches ago with gamepads. It doesnt effect just PC. I had this issue when I played on PS4 and the same issue transitioned into my time on PC....

So the issue is SOME cone based AoEs will not go off using a game bad when you try to activate the skill with the left analog stick in the 11-10 o'clock positions... the 8-7 O'clock positions... 5-4 and 2-1 O'clock positions. If you press the left stick in the positions and use certain abilities... they wont cast until you return the stick to either an unpressed position or one of the 12, 3, 6 or 9 O'clock positions....

The main ability i know has this issue off the top of my had is the DK Noxious Breath ability. It will not reliably cast in fast combat due to this issue.

IMPORTENT: This issue has same impact that Templars had with casting jabs with a gamepad back during Murkmire! When casting Jabs from diagonal positions would prevent the ability from casting.

Here is the issue on a stamplar back in murkmire times. (this is the exact same issue now with abilities like Nox Breath on DK)

PLEASE! fix this before this update goes life. i really need Noxious Breath to be reliable cast in PvP.
