199 A2>R3>SR here.
Ranger 3 - If you want to have your build focus on AOE then this is your choice. Ranger and SR are both skill based AOE classes so the synergy is obvious. Rogue 1 and archer 2 both complement the build well. It comes down to improved multi shot/ swift step VS feint/barrage(must dismount) and sneak hit (which is great but conditional). Barrage does seem to get me instagibbed alot trying when trying to maximize DPS. More SP hungry then QS version but SP pots are cheap. It would nice to kToS steady aim, IMC pls!
QS 3 - Awesome of s single target damage. Max running shot and slap on a grand cross then go. I haven’t played one but I’ve seen there AA damage and it does make me jealous. AA in till runnning shot is down then use your skills rinse repeat. I don’t know how the timing would work but you should be able to use multi shot, concentrated fire and rapid fire ( I hear is crappy) before running shot is ready again. Might be more dependent on linker for grind parties after 240+? (Don’t know) With the knowledge I have now I might have gone QS3 instead but I will reserve judgment in till I’m doing endgame content.
I would say play whatever appeals to you because the game is still young and nothing is set in stone just yet. All classes are one patch away from being deemed useless or meta. Whenever rank 8 is released we will see the so called optimal builds change. I think its more important to play what you like with a specific goal in mind in your case PvE/fun. So I recommend watching some videos/streams of each class in action and pick the one that looks more fun to you.
General tips :
save/huntfor Cafrisun set (lvl15)
save/hunt for grand cross (lvl40 if QS)
save/hunt for arde dagger (lvl75)
Spend the rest of your silver on attributes and pardoner buffs for leveling.
