Well, let me address the reasoning behind my stance, then.

Characters that would have otherwise had abilities beyond what I'd consider 'balanced' for the purposes of the RP have had their abilities toned down for a reason. What matters is not the person's own actions in most cases, but rather the fact that they have access to them in the first place. Furthermore, being able to quite literally generate items for convenience's sake out of thin air may as well end everything. You don't always need heavy firepower to take out a problem, but being able to create a MacGuffin when prompted is about at trivializing as it comes.

Also, characters can be themselves without having limitless power that their source series gives them. I never said she wasn't okay, but that her power as it stands was much too powerful for the RP, and not just in the straightforward damage sense.
