I believe this build needs higher snow than just lv 30. IMO, it would have a hard time against bladers. Imagine: debuffs are successfull, but the blader blocks a strong bow / devil arrow. The blader procedes to knocking down, and quad stabbing the bower, dealing some consistent criticals. With lv 30 snow, you're guaranteed to go down pretty fast.
At 80 cap, the 70:70 could have functioned just fine, with 80 fire / 80 pacheon / 70 light / 70 cold, but now, at 90 cap, it's becoming ever more obvious, that the build is VERY tree-dependent. 90 fire / 90 pacheon / 60 light / 60 cold would be the way to go, but then again, the light is relatively low, giving moderate mobility, and cold makes a huge jump in defense from 60 to 90.
Full STR bow can take pacheon/fire/force, because light or cold aren't that important for full STR. However, a hybrid needs both magical attack and the cold tree. That's the difference, and that's the reason why I think that full STR can take force, but 70:70 can
NOT.
IMO, there's two valid options:
90 pacheon
90 light
90 cold
30 fire (in garments)
and
90 fire
90 pacheon
60 light
60 cold.
Here's a video of BossMan's 90/90/60/60 build
failing against a blader:
http://youtube.com/watch?v=Zqusf8d9QyMNotice he gets nowhere near killing the blader. However, when snow goes down, the blader activates Bicheon force and rapes the bower. In the video, he doesn't even have quad stab!
If the 60 cold build failed against the blader, and the bower came nowhere near killing him because of the constant KD's, then how will the 30 cold build do? Do you get my point?
