I don’t even get why this is an issue…thieves have a very short window of invis unless they spec for it and take all their available ability slots as some form or another of invis… This is sort of like someone saying conditions keep killing me, I don’t think someone should be able to lay more than one type of condition at a time on someone else…
Really no disrespect meant by my comment but it really doesn’t sound like there is any thought of balance involved just someone griping about a thief that killed them…
There are plenty of ways to foil thieves, and they’re pretty easy to kill once you lock them down.
Pay more attention, balance restored…
