So far I have all my Sin skills for my current lvl with the exception of MP eater, which i'm really looking forward to. The class is close to god tier for PvE, it will reach god tier once I get full hp runed up gear, so probs never ;p as despite all the skills i've had i'm still in shop kit bar my quest weapon.
Pve single target goes a little like this, warrs having TDB ofc - Sin>>Archer=Warr (if warr gets a.speed gear they go above archers) >Wiz=Tao.
PvP Endgame prediction Tao>Wizz>Warr>>Sin=Archer.
Warriors are our biggest anti class, they out tank us HP wise and we have nothing that cuts through their armour unlike TDB, the AC gap is only going to increase aswell over time along side non tweaking and the shift run thing being **** stopping all the time for some odd reason which i'm still trying to get my head around, the reasoning, we pretty much need to really outgear them to stand much of a chance aslong as they don't have suns

).
Wizzies MS feels much stronger than 60% here, it feels like my flash dash hits for 2-5 as opposed to 50-60 on trainer and dbl slash about 7-16x2 down from 100ish lol, so just need to hope their shield drops, though when they have finally have FF may aswell just not bother.
Tao's not even gunna comment about the pet speed lol.
Archers and non MS wizzies are pretty much free kills if you get the jump.
