you grossly misinterpreted what he said
he said specs wont be nerfed into oblivion, and they followed that mindset, they barely nerfed outlaw by 3%
they buffed another spec slightly above it but it's not like the gap is this huge unclosable thing
if you did a fight a 100 times the sub rogue may win 60 of them but he wont win all 100 even in 880 gear
and even when he does win.
you either follow the "if its not the best it's garbage" cutting edge high level mentality and deal with the consequences of that (as you have for the past 11 years)
or you do the "ill stick with what i like since the gap isnt big enough to warrant me to change" mentality in which case you're still fine outlaw is still very much competitive
if outlaw ends up useless itll get buffed back, just like sub did.
