Something I noticed when playing on PTS is that the combat doesn't feel "right" and I'm not sure what to attribute this to.
I normally play on EU so have decent ping, whereas PTS gives me 200ms ping, so that might be it (in which case I pity the poor souls that always have that ping). Abilities feel unresponsive and combat doesn't feel impactful. Maybe the later is due to sound (although I don't think combat sounds were touched?) or the damage reduction?
Wonder if anybody else has a similar bad feel on PTS?
