If they really wanted to play into it they could make execute an ability, talent, trait, etc on Between the Eyes. It’s on a 30 seconds CD that drops to 12-18 or so depending on the fight. Currently in PvE crits do x4 damage, not in PvP. Make it do x4 damage on all targets below 20-30% in PvE and PvP. This would allow it to fill the gap of Outlaw being unable to finish opponents at low health. As far as PvE, if it’s baseline I don’t understand why it wouldn’t be balanceable.
Outlaw rogue is S tier right now ONLY because of how well deadshot/Ace/Wits work in our current environment. I know there are other classes that rely on their traits but Outlaw especially so. It’s going to be a completely different game if those are dropped and I doubt it would come close to S tier without some new tools.
