Thanks for the reply as these are all really great points. I'm going to take your advice on the Sharpshooter and Double Attack feats.
I must note, as of right now, there is a limit to the levels. However, if a campaign wanted to have PCs continue to play at level 12, I wanted to build in a rule allowing them to continue to grow. So they can still accrue XP to develop their skills they just won't continue to gain HP, ability increases, or RS (if that is kept).
I see what you mean about the spells. I'm sure some are much worse than others. This might clear up some of the language as well. Although in some instances it may be difficult to separate the varied cost with the description text. I'll take a look at the spells and see what I can do.
I am definitely open to more input, I'll send you an email.
