For the multiple forms, I asked Warden about this and he said it was fine. The reason I'm adding multiple forms is because it's relating to Cameron's third power.
For the balancing act, I didn't include the issues with these powers since most if not all of them more than likely wouldn't cause a major issue other than what would come with learning how to wield the power in the first place, but I can write jot those down quickly.
And I know my powers don't have to be related, I just really want them to. X)
