I did a pure DEX build for archer just for fun in the CBT, because I have to share acc with my bro so that I can only go up to lvl 39. (I am also late cause I got key in the 2nd wave)
In my opinion, pure dex archer is for lazy grinding play style, like mine, I mean the ridiculous amount of evasion make me almost impossible to get hit (almost 80% at lvl 39 in Tenet garden), and kneeling shot scale with dex so I just sit there in one spot and fire away and watch the crit jump (75% crit chance). Boss fight also become much easier, hit rate of the boss from lvl 1 - 40 (cannot say for later boss cause haven’t got up there yet
) is like 5%, I can just sit in one place and shoot the boss until it died. It also good for burst damage (like shotgun Barrage, u get crit like 3/4 out of 5 arrow if u stand near the boss)
Because of my lack of knowledge at the time, I make a mistake of going from Archer 1 > Ranger 1 and did not max my kneeling shot.
The biggest problem of this build is that you will have no damage if playing normally, meaning walking around shooting make your crit damage like other build normal damage), and any mob/boss that use magic might be able to 2 hit you (no dodge chance against them like Vensi, and I have hard time soloing the Specter Master(lvl20) at lvl 18) Beside that , it a cake walk, wait, let me correct, a SLOW cake walk.
