Windel is a little preoccupied so I'll just convey my grasp of his and KoL's feelings on this.[hr]

First off, there is a misconception going on here. You see, it's a GMs responsibility to consider the uses of everyone else's characters and how they can operate in the world of the RP. When they are concerned about the limits of a power, it's because they can see how it could be legitimately used in excess unless addressed outright. In one regard it's an acknowledgement of the creativity of your creation, as annoying a process as it may be.

While you may not intend to use the character in the capacity KoL and Windel imagine, they need to clarify because it still exists until those details are hammered out. So don't stress presuming they hate your character because it receives more scrutiny then most. 

Secondly, the limit to summons is 3-4. No more then that.

Thirdly, and this is entirely me but i know KoL thinks similarly, that Cool downs after the fact for a few days is kinda superfluous considering time skips are a thing. It's a nice thought but at that point you may as well say you can only summon a particular phobia once a night.
