so hard to decide

I can not do it myself and I feel the people on this forum wouldn't know the right thing for me to do but I'll ask anyway
At first I thought having light maxed would increase my magic dmg enough but it seems my character is very hybrid and str based buffs add a lot to my dmg, I don't really like using nukes I like bicheon skills and not being the same as everyone but I'm worried I'll make a mistake by delvling light for fire PLEASE HELP!!!

The most important question is...which would do more dmg if I was primarily using bicheon skills?
