Are any other rogues experiencing this since yesterdays pre-patch:
When I exit stealth while in combat (using shadow strike, for example), there is a 3-4 second delay in my non stealth action bar appearing, which is not good while in the middle of combat.
It is only happening when exiting stealth while in combat. If I’m just walking around, and I toggle stealth off and on, the action bars immediately change over.
I use the other action bar that doesn’t change when you change stances with some stance macros. It’s hidden and only accessible(to my knowledge) by clicking the arrow button(or using a hotkey) to change to. Or by addons.
If you don’t see the 1 with the ^v arrows, you need to uncheck “Hide Bar Scrolling” in Edit Mode for Action Bar 1.
I’ve always disliked the bar changing and have basically been playing this way since Shadow Dance was added. 
Are you talented into Subterfuge?
That’s exactly it!
Did you find it
You are the man! lol
