I start with a Main, master that character until I'm tired of them, but not he game, so I switch to a new character, and so on and so forth, usually spending less and less time with each character, until eventually it just makes more sense just to pick random becuase I'm not sure who I want to play any more, my original main always remains my best character, while I'm decent with most the rest, and pretty terrible with just a few. Random is my way of keeping the game interesting after my initial months of interest have worn off and I need to mix it up keep that same level of interest. If random gives me one I never used much and am terrible with, then that just means a tougher/fresher experience for me, and if random gives me my old main it means a quick victory in the pocket to keep me interested and playing without getting bored since each game is a random character. (And maybe DLC characters to freshen the game too???)
