Can we talk? I spent a career with college educated peers. I think I could have written this letter. But, a lot of folks I worked with could not. This is cogent and compelling. Well written and well formatted. Well done!
On the other hand, WTF? I mean, you had me at "Greetings." As an Arbitrator, my default is "Why not?" What the hell, this ain't MY game! It's OUR game! Wanna lose players before you even start? Tell them they can't play the gang they want to play, and for your own uninformed reasons. Bad way to try to show who's boss.
My LAST cop out...Gangs are innocent until proven guilty. How in the world can you prove Enforcers ain't OP, if you can't even play them (not that you need to prove it, they are an official gang that has roots in the original game, and you CANNOT make them overpowered, anyway; I've tried)?
Good luck taking it before the Judge. Dammit! I just can't help myself!
