i do think ranger3 sacrifice too much potential to learn other job instead.
yeah ranger3 have spiral arrow and bounce shot, and gives better aoe rotation.
but you could take A1>R1>A2>Scout1 for more utility in end-game
or you can take A1>QS3 just for autoattacking (this scales to late game, but… single target)
A1>R3 just gives you aoe barrage (that scales badly in late game) and more skill rotation in end game
it just up to your choices. who knows that R3 Going to be buffed in several years down the patches?
who knows if A2 / Scout1 gonna be nerfed next patch?
enjoy the game. accept that barrage level 15 is an awful scaling skill. thats a fact. but in exchange you have more skill rotation compared to a utility A2>Scout1… (which barely have any aoe, unless u pick late-game aoe jobs)
