So after many TR's I have decided that I am going against the grain and making a pure caster/healer Favored soul with trapping. I have maximized all my casting past lives and finally ready to build.

My question is this. First I plan to be a shifter. Since I won't be getting a capstone as a FVS I want to make up for the lost of DC's as best I can and Shifter allows me to gain 3 Wisdom while raged. Is there anything I dont know about the rage function as a caster that would make this a bad idea? I also like that get an extra 4 con and 4 dex while raged which will help my reflex saves.

I am planning on 18 FVS/2 rogue....but am really debating on going 19 FVS/1 Rogue and just getting evade via shadowdancer even though I have to wait for it (plan to stay at 30 for a long time "months"). Is the addition of the other caster life for DC/caster level worth it over going 2 rogue early?

Any thoughts on the build come to mind that would need to worry about?
