it is incredibly frustrating trying to click the candles (and other items) in the rooms when any of the larger model heroes are being used. the only option is to use friend's heroes to clear the room, which you then have to spend gems if it happens more than once in a dungeon.
this mechanism has been a problem forever, and really really REALLY needs to be changed up. it's incredibly frustrating.
allowing them to interact THROUGH the models would fix it.
