Hint 1 has a double huntress guard Summoner and a double monk guard Summoner. If you're picking up chests, do it with the double monk summoner.
Place your builder Trapper (with app type equipment) and Warden somewhere around Hint 3.
I also haven't tested with TB + Wheeling, but that's for non-AFK and this is for AFK.
Still needs optimizing, but I like seeing most of the mobs die out of spawn. I haven't tested on lower stats. For AFK, you'll need enough damage for the mobs to not get within damaging/throwing distance of your towers. Otherwise you'll need to tweak it a bit with reflect beams and/or a Holy Bulwark / Forest Golem.
