I made a build for doing quick stuff like dailies or skyshards in delves, putting alchemy glyphs on jewellery and using a bunch of speed/invisibility potions.
The problem is, maybe 20% of the time, I'm pulled out of stealth when passing by an enemy for no apparent reason.
The duration is still going. I'm not attacking, nor using anything that will cause damage.
No dodge rolling, blocking, no interacting with anything.
Sometimes I will run past a bunch of stuff, then at the next bunch, I've somehow aggroed and detected.
Sometimes it will happen at the first mob I pass by.
There are times when I've ran past a bunch of mobs with no problem- then, later while returning through the same mobs on my way out, moving in exactly the same way, I'm suddenly detected.
Its infuriating because its so unreliable. One fifth of my invisibility potions are just wasted gold, and I would be better off just mindlessly grinding through mob after braindead bloody mob. Why have cool stuff people can explore and experiment with if they just don't work and you just have to kill everything?
There's, of course, no documentation anywhere on how they work, or how they might fail and its sad to say that the safe bet is that its not the system, its just one more bug.
Has anyone else had this experience? Are there known circumstances that will draw aggro even when you're invisible?
