And with character with a Archer C3/Ranger C3/QS C3/ Falconer build, you have a goddamn Anti-crowd bunker build that specialize in taking out ranged enemies who lined up to chase you out from your bunker (Full Draw, Multi Shot, Rapid Shot, High Anchoring, Bounce Shot will be your skills to take out enemies fast, while Heavy Shot, and Stone Shot, and Barrage, and Full Draw with knockback attribute will be your skills to keep enemies out of your bunker). Especially if you’re using max Swift Step and max Running Shot, you can kite them to your bunker or quickly escape from there while still auto attacking them!
Edit: Oh, and don’t forget about Hanging Shot, you can literally get in and out of your bunker or safe zone with both Running Shot and Hanging Shot
There are other bunker builds, which is also present in the old system, the most known one is the QS/Sapper/Falconer build. However, they’re more specialized in taking out melee enemies as Sapper can’t take out enemy that far away except for their Claymore skill
It all doesn’t fall to your builds become weak or not. It simply fall either you want to be diverse or specialize in one task/area.
