in the future, if you’re playing with a variant which adjusts the standard assumptions of the game, you should probably mention those.
It did not occur to me at the time of my original post, but you're right, I should have provided better information.
Why does everyone else feel so inferior is my next question? A Fighters DPR with a bonus archetype should be feeling pretty good alongside that, if not just hands down better.
I don't feel inferior. I do very good damge myself, in spite of the fact I developed a character around control (trips and shoves). More importantly to me, I perform my denial abilities very well. This post wasn't about dissatisfaction with my character, it was about a conversation we both had where he was concerned he was hurting game balance/experience for other players. I wanted to make sure we are playing correctly and that we were not missing a rule.
I also still want to understand how a Lvl 7 character on average is doing enough damage to kill on level opponents in a single turn to the point where they can drop a second opponent. What opponents are you all facing at level 7 that your son is killing with that kind of consistency?
I addressed this in the post you replied to. He does not take down on level foes in 1 round. It is mostly encounters with multiple lower level foes (though it did not occur to me until typing my previous reply that his best output was against lower level foes).
