It's completely unfun to play against, There is almost no counterplay with to it and still allows thieves to deal huge damage bursts and almost instantly go back to stealth. Even stealth traps aren't good enough because deadeye can cleanse revealed. Either completely change the way stacking stealth works or give us a lot more access to the revealed debuff. I mean every class, And atleast 1 skill/utility.
Edit: Just going to add that this isn't limited to deadeye only. Both daredevil (especially with bound + BP) and base thief can effectively keep up stealth permanently. Its not fun.
