I meant that not only regarding to the build, but also while interpreting your character, even though I listed a book and a class as examples so I understando your confusion.
Sorry about the delay, the last few days have been rough with ammount of work and the forum being inconsistent was not helping.
From what I can see, the LK seems to have more options regarding the use of utility talents and battle burns seems to allow him to use his talents more often, so an increase in utility and power level overall. Since Kineticist is mostly focused in blasting, I don't think it will do much hard allowing the class, so you can use it, but if things get out of hand I'd like for you to be open for some changes.
Also, since I'm just responding to this now I'll accept your sheet if you can post it today. Again, sorry for the last few days of absense, but I need to keep the dealine I set myself.
I'll make the selection tomorrow, and since I'm opening this exception, anyone who has already submited a character can go over it again and make changes (things like itens can be altered after the selection is made, since the players will have more information regarding the campaign).
