I'll start by saying I really enjoy HoS. I'm currently playing on Android, Normal difficulty with the default heroes, and got as far as the Storm Bastion.
However, one thing that really bugs me is that some dungeons (e.g. Bone Ridge) get repopulted after certain in-game events. Wading my way again through the same sets of monsters feels grindy and repetitive. Is there any way to avoid these kind of repeat combats?
