Plus I find it a great learning experience. Crafting a unique OC can be difficult and so people often default to strapping as many colors. And attachments, and unique backstory too them. But that can make it hard to cosplay that character, or makes for really shallow character story. I like to say it's not what you've got it's what you do with it. Crafting a deep interesting oc is much more fun in my opinion than just always having a tool for the job. Not that there's anything wrong with being a Swiss army knife character, just that RP helps players develop more grounded characters.
