No, not using Stealth (since I'm only getting close to adding the rogue NPC now).
However, I think I have it fixed.
Just to be on the safe side, I grabbed a noCD even though I bought a retail box. Then I just avoid using 9-Cooldown on the trainer.
It seems to make sense that if cooldowns never time out that negative effects (poison, fire, rooted, etc) wouldn't cooldown either, right?
Oh well, the trainer works great now. Thanks for checking in all the same.
I've always used the instant cooldowns, and never had this issue. However, when I accidentally turned on the rogue option (was typing on a web page) I had the 'burn' debuff on me permanently...had to kill myself to finally get it off. I've since customized the trainer (CH rules!) to put the rogue stealth option on a key I never use, so I won't have this issue again!
