I really like archers after playing them so I don’t regret that at all. I probably won’t be going back to my swordie any time soon to be honest.
I’ve currently got 2 different archers both around level 90. One of them is Quarrel Shooter 3 and the other is Ranger 3. Quarrel Shooter is a lot of fun and have incredibly strong single target/grinding at my current level, but their late game scaling is poor and their AoE sucks so they’ll probably get really weak in the long run, regardless it’s the most I’ve enjoyed any character up to this point so I’m going to keep at them for the moment
. Ranger 3 is not nearly as fun to me but once they build into Fletcher they get some absurdly strong skills with no CDs. Fletcher is flavor of the month as one of the most OP dps in the game and it seems to be for good reason.
I can’t comment much on this new build you’ve found unfortunately. I never looked into Barbarians when making my Swordie so don’t really know anything about that class or what it offers to Corsair. My best guess for rank 7 would be Doppel, the build seems to be based around lots of buffs and Doppel offers another good one. Plus whirlwind is supposed to be excellent. Only other reasonable options would be Barb 3, Corsair 3, or Dragoon. Corsair 3 is pretty weak tho and I don’t know what Barb 3 offers, Dragoon might be fine though.
