Hello,
I have mentioned this in other threads but here feels like a good place to iterate this and I dont seem to be able to find a post about it.
There is a very annoying bug with stealth.
When a player/mob (especially mob) is channeling a single target ability at a Thief and the Thief stealths the ability being fire at the Thief is not interupted.
Imho the channeled spell should be broken as if the Thief has run out of line of sight. Effectively that is what they are doing. As it is at the moment this doesnt happen.
