I would agree on auto-play not being optimized. Though, factually: Support does react to a lot of player feedback & wishes!
All it needs is a smart AI, reduction of the oversized zoom (display size), and sufficient energy to actually play the game instead of grinding & farming for more red gems to buy energy with.
I had my losses in the Spider dungeon, but in 2019 I returned, failed to reactivate my old account, and started anew. This time my group was full of 'attack-em-all' types, and I defeated spider earlier & easier on AI (auto combat).
Try figures like sister militant, or dhampir, or similar. As a secondary team, which simply has not much need of skill-choices. Could make sense to take a leader, who has healing or revive dead, as an aura skill (passive).
Good luck!
