I have the same thoughts as you for my second sub. I'm almost 95% sure i'm going to sub as an ES since most my friends play nukers, and i would then be a great asset to them.
The general (but not absolute) rule is: ES if you party mostly with mages, WK if you party mostly with archers, PS is if you have melee friends.
The rule I preffer: what is uber today might be completely gimped tomorow, so play what you like.
All the pets have pretty much same stats and skills, but if u at any point wanna solo (no oop buffers or anything), u might want to play ps, coz of the vr passive of the shadow.
Yes, it is. It paralyzes the mobs with a very very very good landing rate. Meaning, mob is paralyzed, your kitty can attack, you can attack, and no damage.
I wouldn't trade my para cubic for anything else ;)
If u wanna lvl fast u still go for PS, phantom cubic has 3 effects, one of them being hex, lowering the pdef of the mob, which means the mob dies faster, it being paralyzed doesnt mean it dies faster.
