Its pointless to use force and not have it maxed out. Either use force 90, or do not use force at all. When u have force lvl 70, almost every debuf/vital wil get resisted by other lvl 90's. U really MUST max out force if u wanna use it, force 70 will do no good at all when u are 90 and fighting other 90's.
I would recommed pacheon/fire/force 90 and cold 30. U wont have any speed but u wont need it anyways with bow range. And for pvp u will be missing out on phantom's, but who needs those with decay + division

Decay + division on ur opponent is 1hit for sure on pure ints/hybrid ints, so they will be no match for u anyways.
If u decide to drop force, i'd go cold instead of light (preffer defence then the speed, there's always the speeddrugs left, only issue is u will be missing out on phantom again).
