So right now the core classes are like BM, SR, maybe Assassin, etc.
There are a lot of ‘support’ classes and they do different roles, most people are going to go for damage (Enchanter, Corsair, Asassin[Hasisas buff soon]) or utility/farming (Linker/Thauma).
Outlaw provides a bit of an odd mix that puts it in a weird spot. Primarily I would take it if I already have some evasion buffs but I’m not capping out my evasion (50% btw, 25% with 10+ mobs aggro’d to you).
It also provides some debuffs (Sand/Brick), Sand having pretty good AAR, and provides some good damage skills that give temporary invulnerability of a sort. The aggro is just a nice benefit, but the range isn’t good enough.
The biggest problem with Outlaw for a defensive class choice though is that Evasion is already somewhat simple to cap for most circumstances, so it’s only useful against some bosses you don’t Evade at max (50%) anyway. Also cap on Evasion being 50% makes it a non-viable form of primary defense. If Bully was changed to Dodge or you had some form of Dodge/Block to add onto it, it may be more viable. I personally would not recommend using these as a means to need less PDEF/MDEF unless you were able to have 50% Evasion, 50% Dodge, 50% Block as a minimum as these three roles make things a lot simpler. If one of them could get as high as 75% you might have something worthwhile. You can compare this to stacking these in Path of Exile or other similar games.
If outlaw’s bully was changed to Dodge or some sort of separate roll from regular Evasion, it would make the class much more viable, but right now I don’t believe it’s defensive utility can stand against Assassin Hasisas, Enchanter’s entire kit (Wastrel Sword viability, Block, Damage), or Corsair’s Brutality.
Even with the changes coming up to make Bully basically last forever. (Mine already lasts well over 300s as is when I had it)
