Body morphing
With replaying the previous games I'm honestly happy that body morphing is taken out. Sure the devil horns and halo above the head are cool and it's sad they won't be returning but I hate that when I level up my character they just become more blocky. The only morphing I don't dislike is the Will level ups giving you borderlands siren tattoos. If you enjoy body morphing that's cool but when my character drastically changes how he looks for the worse I'm not a big fan.
