*note* if you don't plan to gold wheel, the minions aren't necessary. But if your stats are lower they def do help
I run upper + TB wave 22 and aim at point 4 by the spawn with my upper. If your shots are going up the air vent just stand on the warden towers or golem to get a better angle. TB sort of aims at the point 5 on the path
w23 (or whenever you're done upping) - I run summ with hunt + app on warden stack, TB, summ with hunt + squire on guardian stack, and builder warden
if you're wheeling replace the summ with hunt / app with a wheeler that has a hunt guardian. I wheel 100 / 400 / 800 ish enemies, but if i forget i usually just wheel around 100-200 and then before 800 to ensure TB doesn't die while golden ogres are alive. I was able to wheel 23-39 just fine following these numbers.
