I've been looking around a lot, asking friends etc. about how the playthrough system specifically works in Borderlands 2 I am completely new to the franchise but have a decent idea of how things work.
I simply ask what specifically happens/changes in each playthrough , such as if gear will level up with you, at what points gear levels to you and so on. I may end up asking a few questions too. (Don't take it to heart about your skill at explaining things, I'm a slow learner :P).
P.S Bear in mind this is the Handsome Collection, playing on PS4. I will have all DLCs.
