I understand, but being that this a power RP. And I really don't like absolute powers or powers without limitations, it gives me the ability to maneuver in the RP.

By giving it specifics, just say like DnD, it means members can't pull things out of their ass. I am not saying you will, btw. Sadly RPing in the past a lot of my specific rules are because of experiences in the past. 

Specific details allow me to reference to the sheet and not have a member going

"no he can hit the helicopter with his fireball"

"the helicopter is flying away"

"yeah, but he can throw his fireball at him"

"how?"

"because he can"

This gives me a way to know what your character specifically can and cannot do, so there are no arguments, no problems in the IC with distant, radius, time or duration of abilities. This gives your power clear structured limitations. 

You're already accepted. But I do like to have them and I have my reasons for them. It prevents god modding, or prevents um what's the term....when a member does something to always win because their powers have no limitations and "just can do it".
