Bowling infusion, and it's the only one that matters.
Good to see we're in agreement then. I'm not sure what the point of everything else is.
The point is that you keep bringing up irrelevant things as arguments against the power of the Kineticist. You put forth the Sirocco Sorcerer as a counterexample, but he has a lower BAB and no iteratives either. You would naturally object to anyone bringing those up when discussing the sorceror's power, so I can't understand why you do that for the Kineticist.
I don't think anyone is denying that Kineticist is good at dealing damage, just that dealing damage is not all that there is to a class. In comparison sorcerer has buffs like haste, legendary proportions, etc which help in various different ways and act as a good form of utility. It also has very good crowd control (Sirocco, Stinking Cloud, Mass Icy Prison), stat drains like cloudkill, defensive tools like mirror image, seamantle and fiery body and on top of that, it also has ways to deal damage. Sure, it isn't going to instantly kill everything in a single cast unlike kineticist at level 20 (unless you stack the DC of weird sky high, you can then one cast kill many enemies within the game with a DC 43 weird) but it does good enough damage in addition to everything else.
The point being, if you were to compare the kineticist to other classes, it doesn't look as broken as people make it out to be. It is only when you focus on damage to the exclusion of any other party contribution that it looks "broken."
