I'm very supportive of GMs' decisions and how they want to run an rp, but I hate it when a GM is fine with a character's main powers, but gets nit-picky with secondary powers that were for the purpose of merely adding to the theme of the character. I had a GM do this to me because he wanted characters to not mirror each other in powers, even though there was only one other with a power that was a slight bit similar. Also it only had to do with the character having the increased senses of a particular animal so it wasn't superhuman strnegth or durability or an attack, it was just a minor ability. 

So yeah I understand that it's great for a roleplay to have diverse characters with diverse powers, but there's almost always going to be overlap and getting nit-picky at powers that don't make the character OP or used to much does not help with getting people to join.

I know this has been brought up before, but Casual gets so much drama that it can kill rps
