Hello there.
Cloakingās bonus applies only to autoattacks from what people reported so no, it doesnāt affect backstab. Burrow I donāt see that useful, you canāt use skills while in it, a bit like a kneeling shot I guess, just without the bonus. Not sure how I feel about it, Iād take it either way to test it.
I also want to test out a rogue eventually but keep in mind you most likely wonāt be able to do a full str build early on - you will be struggling, you wonāt be able to use your skills as they will cost a lot SP and you will be either constantly sitting down or raging at your archer/ranger. Consider an SPR build instead so you can spam those skills when possible, they have a good enough damage on their own if levelled so you should be fine with levelling to rogue, then you can later on reset.
Iām not convinced about critical - again, SP drain is what it is for me. It might be good later on but not sure about it honestly.
If Iād be doing a Rogue, I would try to make it so you have some ways to either close the distance which would be for example oblique shot slow, flu flu from scout, confusion from wugushi or for example coursing from hunter ( itās most likely the worst option because not only is the pet a money drain, the moment its dead youāre going to have a though time using it for your cc purposes ). You also do need the aoe damage Iād say, but that can be achieved in many ways not just through ranger. Archer c2 or c3 with buying obliqueās damage attribute, a good bow and full spr build will literally carry you through most mobs and multishot in those circumstances should be a good enough burst to handle bosses.
I guess it all depends how you see yourself playing, between all of those scout seems the easiest options as you can just bypass some of the needs for cc, so for rogue it still seems the best option for pvp even if a bit lackluster.
As to whether Iād go ranger c3 or scout c1, you can answer that yourself when youāre at ranger c2. Realize this, rogue has no way to deal aoe damage other then lachrymator, and no one tested the damage from the attribute yet to my knowledge, there is reason to doubt whether its any good. Keeping that in mind - when youāre about to change classes you should just sum up your experiences and answer that for yourself. I see merit in both ways but scout is definitely the better option for pvp.
When it comes to SR between rogue, I actually see SR far better then the backstabbing counterpart. I would myself be building a ranger into an SR or ranger into wugushi into SR even. I think archer c1 - ranger c2 - wugushi c2 - sr will be a balanced build between single target damage from poison, srās spam - if you can afford it SP wise, aoe damage from both archer (oblique spam, even if itās lvl 5 it will last for some early levels), ranger obviously, wugushiās throw gu pot and later on SRs retreat shot and caracole. The movement speed from mounting your companion is also a very big buff, even more when fighting large groups of enemies.
The pistol is already an off hand, you use a crossbow in your main and it works out. Not sure if thereās a difference in synergy, the offhand doesnāt seem to be adding damage at least from what I saw on a rogue clip some time ago, but I havenāt tested it myself.
Iād say give the wugushi a try, it will help with aoe through throwing pot - mounting and dismounting is instanteous so itās not that much to throw it down and ride away into the sunset ( or actually circle the poison so mobs get more damage ) while the tick damage is really good too and will help a lot vs big targets like elite mobs or bosses. Apparently wugong gu can also work as an aoe but you actually have to level the skill ( with each level the poison jumps to one more target from the main host onto a nearby mob upon being attacked ) and might additionally help with some big stacks of mobs.
I wouldnāt know how to build an archer - ranger c3 - ??? - SR because I canāt think of anything that would be worthwhile past ranger 3, so if youāre bent on it I canāt really help you.
Either way, I hope I have been of assistance at least to some extent. Hope you will share your experience whatever path you choose!
