Archer skills seem fine. I would probably go Oblique 4/Full Draw 1, but that’s just a matter of personal preference. Oblique is more useful as a damage skill since it has no cooldown, and Full Draw is best used for its utility rather than its damage anyways.
QS Skills…
I’d drop Teardown to 1 personally. It’s cool as a knockback, but generally your Pavise is better served blocking attacks rather than exploding.
If you want to do PVP, you should definitely get Stone Shot. Picking 1 is sufficient, if you’re using a Grand Cross and get the attribute 3 stones per cast is plenty. I maxed Stone Shot for leveling (+50% against Plate targets and hits 2 on top of the stun, which is not listed in the skill description), so with 0 cooldown its a very powerful leveling tool until you get Running Shot. As long as you have SP pots to chug. Which you should, as I’m 147 now and still haven’t run out of tutorial pots. Stun breakpoints for Stone Shot are 3,5,8,10,13,15,18 so best spot to have it is probably either 8 or 13 (since you get a break point and Grand Cross will push you to another break point).
Rapid fire is…kind of limited in usefulness. It’s somewhat difficult to aim, and the damage is nothing special in comparison to Running Shot. the attribute is great if you or anyone in your party has dex in their build, so I’d definitely get it at least level 1. I have it at level 10, and while I wouldn’t say I regret taking it, I’d seriously consider leaving it at 1 if I were to skill reset for another reason.
I’m personally not a big fan of high levels of Caltrops. I have it have 3+2, and I can’t really see many situations where I’d need more of it. Maybe I’m just not using it correctly, but if you were desperate to get points somewhere, I think Caltrops could survive with at a few levels lower. Same with Pavise really, but I’m a bit biased there since I won’t be able to use Pavise very much since my build goes into SR after QS.
For scout skills, I’d drop FluFlu to 1 and get Flare Shot 4. Flare shot is a decent AoE ground target, so it can hit burrowed enemies and I imagine caltrops+flare shot would be great mob control while you were leveling. It would also add a decent damage bonus against an enemy while they wait to recover from your 7/8/9 second stun from Stone Shot. I would personally also drop Camouflage to 4 and get Flare 5, but I don’t think that’s an absolutely necessary change.
For Rogue skills, I’d say Vendetta is of limited usefulness. It’s not…terrible while leveling, but I wouldn’t say it’s great either. Also, Feint is pretty unnecessary to level as enemy evasion is virtually non-existent in this game, especially if you have any real dex in your build. The spin attribute is good, so I’d still get Feint 1, but I don’t see much of a reason to get any more of it than that. Capturing seems useful to me if for no reason other than to swipe heals and use them later, so I would probably move the points from Feint there.
I would probably leave Vendetta at 0 as well and use the points to max Backstab at Class Change.
I think Teardown has very situational use, and in general your Pavise is best used in its own right as a defensive measure. For my own QS characters I generally only put a point in Teardown (since as you mentioned it’s really about the utility), but if you’d like you can put more, since most of the other QS skills don’t require maxing either.
