Alright, I think I got the basics of the Kineticist, although I'll have to read all the different talents in detail to see what I would want to play (although no danger of that, I am currently GM'ing two groups with many a month to go for both campaigns).
I'll say that putting nine very long and complex descriptions of class abilities (and some shorter ones) before you even get to see what all those wild talents and infusions and thingamajigs can do, made it definitely a chore to read through the class. It's doable, but it definitely is the most complex D20 class I ever read through and I've never had this problem with any other Paizo class before.
I guess that's a sign of its versatility, but, man. I'll be looking at the other classes throughout the next days, I hope they are less complicated. I hope that the Occultist really is the "Harry Dresden" type of class, which I remember a developer saying during the playtest.
