I posted about this problem in the General Discussion forum. Drop the “perceptive pocopoc” buff. Every time Poco gets “excited” by seeing something interesting he takes you right out of stealth.
Go ahead and give it a shot. Turn the buff on and go stealth. Run near something that makes Poco excited and BAM!!..out of stealth.
I no longer use Poco. My addons know where all the good stuff is anyways 
Ahh thanks for the tip, I will try that
I get destealthed every time going through the maze doors in Mists.
And now with 9.2 the encrypted relics immediately break me out of stealth when they’re engaged in combat.
Blizzard just can’t get their sh*t together and it really shows.
Dragonflight, still happening
As Sassin rogue, literally just watching people in stealth… puff, knocked out of it.
MULTIPLE TIMES in a row
