I don't have every feat memorized and every rule 100 percent down. And I played D&D 3.5 before Pathfinder for 15 years. It took me 7 to feel strong as a GM.
I love the banter in the threads, but sometimes the aloofness comes out. Like it is here. Remember, everyone on here isn't an expert.
I think part of the issue is that you want to address one problem and have gotten a lot of advice regarding the means by which you can fix a different problem.
You would like to know how to fix a social problem -- one of you wants to play a different kind of game than the rest of you. He wants to play in a mathy, games mastering way that you (and maybe some others) don't enjoy. The solution to that problem is really having an honest chat about how he does that. Some quick suggestions:
1) Push him to play something that is really good at making others better. Like a buffing bard with a designating gun.
2) Tell him his build isn't fun for YOU as the GM. Work together to rework his PC.
That said, the observers saying that the warpriest is simultaneously broken/poorly built/and maybe not that good are probably right. They are just solving a slightly different problem. Albeit, one that MIGHT be helpful when trying to solve your other problem.
It looks like his build is illegal in several regards.
It looks like his build, if it conformed to the rules wouldn't be all that good.
And, it looks like some of your expectations may be off.
Those are 3 different problems, perhaps with some shared solutions.
First, I would look at his rule issues. Show him that what he is doing is really not allowed.
Second, given his rules issue, work TOGETHER to build his PC. You can go spell by spell and feat by feat. Make sure you know how they work.
Third, make sure you know what to expect. You seem bummed by the fact that he dropped two CR 10 kytons in a turn. That isn't a crazy result. Nor does it indicate that he is crazy powerful.
Fighter starts with 16 strength. Adds +2 from leveling and another +2 from magic
He grabs a +2 greatsword.
He takes bog-standard feats: weapon focus, weapon specialization, greater weapon focus, improved critical, and power attack. He has weapon training 1 and 2.
His attack line at lvl 11 is: +20/+15/+10 2d6+23
The average damage (counting the possibility of crits) is ~75 against a sacristan kyton's AC of 22.
A core-only, no bells-and-whistles fighter will do ~75 damage per full attack to your CR 10 kyton (the sacristan, I assume). It has 126 HP, so it is likely to die in 2 rounds. If anyone in the party buffs him (e.g. someone casts haste) and he gets a little lucky, he may drop 2 in one turn. That is a bog-standard, no-frills fighter. Generally speaking, that represents competency and proficiency within a role. It is neither wildly expectation-breaking nor does it represent a character facing its favored foe.
If that's surprising, you may need to recalibrate your expectations and work with that. You want to run a game that differs from some core assumptions in the game. That's great, but it is a fact you need to know.
