One of the reasons i love Homestuck: At one point, all of my ocs and characters in any works of fiction i have made were simply Homestuck ocs. Due to the class and aspect systems, the ocs i made were so detailed and unique from each other that i could never bare to throw them away, and eventually made story’s and worlds separate from Homestuck for them to live in.

Exactly! Homestuck provides a set of hyperflexible tools to develop your OCs- The powers the Classpects grant as well as their personality traits, the Sylladex, Strife Deck and Alchemy System give them the Freedom to personalize everything to their liking, their Land and Quest reflects challenges made personally for them, Time Shenanigans that allow the exploration of various routes and paths things could have gone, even just the text color and typing quirks add so much personality to a character.
