For the love of all things good please make it so we can change our color, I dont care at this point if its a pay option like 1-5bucks. I picked green and it was really cool on the starter armor, but other than that all other armor green looks the worst to have been picked... PLEASE...!

Which is a much older, and popular, version of your suggestion. Come on, go over there and add your voice to theirs!
P.S. I don't think your 1-5 bucks idea would be popular over there, but thats my thought.
