I am mainly focused on PVP & Boss fighting, but i'm curious if Defense is worth building or up or if I should let it lag behind? I was thinking of keeping attack/defense even, but since defense only helps with boses wasn't sure if ti was worth while or not. Right now i'm Energy: 1000 Sta: 625 Atk 1200 Def 500 HP 60000
Defense plays a important role on PVP. If you give crappy exp back, all you will end up with is people setting counters on you. Plus when people way lower level find out defense is lacking, you will get hit by them.
