Disappointment.

Bonus pot has worser pots than nebs, and can have whatever the pineapple they want, like atk on armor and def on weapons.

Woah now, how is bonus pots worse than nebs? That 6 atk is already better than your 4% all stats. Also, to be honest here, I've scored 5% stats on a unique bonus pot already slapped on with 11 atk bonus. That's both better than anything I can get on a neb (exception of weapons). Personally, the biggest feature for bonus pot for me is the extra atk on armors and accessories, followed by getting dmg cap increases on weapons. The biggest issue is how much NX you would spend, which would just slap Nexon tons of dollars.
