Every method has its own strengths and flaws, I realize this, but that aside, I generaly try to upgrade Active Modules (including multipurpose) first, then main weapons, then passives. I just need reload speed/strength of the module over everything. I sometimes (just for fun) fly to battle with no passives/mains and just use modules. (Funny thing is, I still own, I’m just a bit more poppable. X3)
