Huge thanks to Drawing_Pin for the strat I used to beat this! I deviated a bit from their build going for staff to undermine enemy formations/density, as well as going for more of a greedy economic build. I still lost a bit too many farms compared to other, failed attempts, but a win's a win lol. I built the trap harbor at the end to bait the wasps away from the blacksmith so I could have the final upgrade for wave 11, but I should have probably gone for ranged armor or dmg instead.
A huge problem with not taking any damage upgrades for this is that enemies heal faster than you and your towers can deal damage to them, so at the very least keeping the hero unit alive and probably some archers too is critical.
