I play a Sniper and ever since Patch 1.1 I have had incredibly bad ability delay, granted as a Sniper before the patch is was pretty bad anyways, but now it has kept me out of Warzones it is so frustrating.
I will stand in front of someone, stationary and have to literally smash the hotkey to make an instant ability go off. Grenades/Darts seem to have the worst delay. The delay takes anywhere from 2-5 seconds sometimes, granted that's if the ability actually registers, sometimes nothing happens.
While I experience this in situations with the target in front of me, not moving with me standing completely still and facing them -- I can't even go into how terrible ability delay is when you attempt to kite a target now or when they are bouncing in and out of your max range.
All of these problems I'm having mind you are from INSTANT abilities that are far from the word "Instant" and need to be addressed. Whatever you did to the UI has completely fubar'd the ability to play on my Sniper.
It was tolerable before the patch, and I seriously hope it gets fixed or addressed because I enjoy PvPing and if I can't do it without this frustration (which I doubt I'm alone in) I can see giving up on the game entirely in the future.
