Its already like that , btw.
As for the timing thing, well, it is how it is really, everything is already decided by your ping pretty much, just gotta adjust to it or randomly time it at some point, theres alot you cant really react to anyways so its alright.
Yeah, i did, once or twice last few months, very useful if i say so myself. -s (it was possible even with 50% dmg reduction (350 x 0.5 = 175) you lived with 25-50 HP
No, its not good at all, look at you dmg mitigated in average then tell me thats an useful thing to have (mind you Dmg mitigation also comes from Deadeye)
Souls games have I-frames on their roll btw, it would actually be like playing Dark Souls if it had i-frames.
Achtually he can survive up to 899 dmg in those 0.5s and have 1 HP left, doesnt make it all that useful anyways.
