Tried every possible combination, still happens.
Not happening there.
Kinda feels like a "lag" issue. In pve I can stealth and use stealth attack 0.0000000001s later. Feels like I got so much delay in pvp that it doesnt work and by the time the server lets me stealth attack, the 1-4s of stealth are already over.
But my ping is very low, ~30 everywhere.
Just some tests:
Steal (1.25s stealth) = literally impossible for me to stealth attack
Blinding powder, heal skill, dagger 5 (4s+ stealth) = 50% chance
Waiting in shadow refugee (10s+++ stealth) = very likely to work
My config (changed it alot to fix it, not sure if its the same as before)
double click to attack/interact YES
right click to attack/interact NO
stop auto attacking on target change NO
auto targeting NO
promote skill target YES
melee attack assist NO
allow skill retargetting YES
