I am currently building a Level 4 Kineticist, and one of the downsides to the class is its weak Will save. As such, Iron Will is definitely going to be taken at some point as I level, but I'm wondering how safe it would be to take an 'instant gratification' feat like Improved Initiative or Weapon Finesse for level 5, and postpone the 'boring but necessary' Iron Will until level 7.
In the meantime, I've taken Birthmark over Indomitable Faith in an attempt to soften the blow. My reasoning for this is to have a better effective save against the spells and abilities that make Will so important, I can get away with a weaker save against anything that doesn't fall under the Charm and Compulsion criteria.
Is this logic sound? Or would it be more critical to take Iron Will as soon as I hit level 5 before anything else? This is for a RoTRL campaign, and this character will not be starting out with any gear that boosts saves.
