If for some reason anyone is checking out this topic thread looking for the most optimal/highest damage skill setup, here are 2 skill builds that you should try out. & I'll add a few good damage gear sets that you could use to improve your build even further. Let's begin with the skill builds For the first one, it's a very consistent build with pretty high damage output that mainly focuses on solo target clearing. Main Skills: 5/5 Merciless 5/5 Stealth 3/5 Gouge (To stun specific mobs in a dungeon while moving through) Expert Skills: 4/4 Extermination 4/4 Jump (<< The build that I run mostly for PvE activities). 2nd skill build is pretty much the same as the first skill build, but with 1 tweak to the Expert skills, which is rather than having 4/4 Jump, you could run 4/4 Sinister Strike, yes you might lose some damage in return, but running Sinister strike weakens the target so that your party does more damage towards that specific target. Not only that but if there's 2 Rogues using 4/4 Sinister strike, you can potentially keep a boss permanently weakened & can lead to faster dungeon runs/spam completion. Those were the 2 skill build sets that I find to be the most meta for now, even if you don't have an Attack speed gear setup, the new & improved Extermination really doesn't need a build to make it viable. & speaking about gear builds I did mention at the beginning that I'll add a few good damage gear sets. there's 3 damage meta sets out there that I think every damage class should get/use one of them at least, 1st one is the the full Nadir set (Crit/CD) this gear set is just an all around beast of a set, it offer's a lot of stat bonuses that can't be passed on about. same can be said about the 2nd Nadir set which offer's more Penetration than the Crit/CD set. Those are 2 gear sets & the last gear set is just, well... It's a mix of the two, so rather than having more CD or Pene, you'll go with 2 pieces of each sets to get more Crit. Feels like I've said what I needed to say. So, without rambling any further, let's do a quick summary.
1st skill build: 5/5 Merciless 5/5 Stealth 3/5 Gouge 4/4 Extermination 4/4 Jump <<(Highest damaging build)
2nd skill build: 5/5 Merciless 5/5 Stealth 3/5 Gouge 4/4 Extermination 4/4 Sinister Strike
1st gear build: Full Nadir Set (Crit/CD)
2nd gear build: Full Nadir Set (Crit/Pene)
3rd gear build: 2x Pieces of each Nadir sets (Crit ++)
