I am pretty sure they won't be a bother. I mean each character is so different that seeing them all together interacting in more than one period is pretty cool. And your characters are nice. There just different, but different is okay.
I'm normally more of a jump-in roleplay person tbh. I have done a few real rp's, but same with some of the others, I haven't done one this big either. To get psyched for it, I have to imagine the characters as actual classmates. XD
I think Warren might let Silice come demonstrate fight with him in first period from time to time. Get some more intake on fighting styles and what not.
