Yes, Jesse asked for people to post issues with characters in this forum. This is the right place for this post.
This bug is one of the most annoying things about Teebo as leader - in my experience he's rarely in stealth because either his leader doesn't proc when he's not in stealth, or it procs on the turn after you use his stealth special and it takes out of stealth - you end up with only 1 turn of stealth from his special ability.
Hoping for a fix to this asap.
Also, it's nice that he gets some potency at G10 - but realistically, G10 for Teebo is 6 months to a year away at current gear obtaining rate, and so instead I suggest some of his potency be moved to lower gear levels, so that there is a smoother progression of potency as you gear him up, rather than being basically a lump sum at max gear.
