Well, as for the tooltip I think you guys are getting far too picky.
Nevertheless, the idea of adding like a 10% Power bonus to all Shots that don't previously use Power is not a bad idea. In truth, the only thing it could do is increase the strength of Shots based on other things ( Blood Shot, Mana Shot, Blink Shot, etc. ), and make the Power bonuses given by Guns always matter ( like the high bonuses of the Master Guns ) at least a little.
I will make a note of it. It should be in the next release.
