I actually have 3 characters.

The worst part about multiple characters is getting them to end-game, but once you hit that point, its simply maintaining them.

It's great to be able to do DOs multiple times a day as well as TACOs and XQCOs.

I personally hate TACOs with a seething passion, but not doing them makes earning meseta more troublesome. 3 characters lets up on this burden.

Another thing with multiple characters is that a single character only has a 20 skill tree limit for all classes. So if you eventually end up owning 20 skill trees (lol), you cant get anymore, you have to start paying to transfer them between classes.

Multiple characters also means being able to have multiple chances at drops for like Falz Losers and Elder.
