My stealth abilities has a 30-40% fail rate
I concur that this is one of the annoying bugs for me currently — that the auto-attack breaks through some stealth abilities. Most notably, the traited stealth on steal (making that traited special almost worthless). Would be wonderful if it could be fixed so that auto-attack is cut off there.
The skill “Throw gunk” (The ethereal field) from stealing will automatically break any stealth if you have it active when trying/using/being in stealth. Pretty annoying and I can’t think it is intentional.
