I think we need more and different quests and achievements to keep us more alert during battles.
Like “Kill 2 targets with headshots” or “Complete mission 6-4 using only one hero”, or, you know… “Complete Gorgon 55+ without manually activating a skill”. Just small things like that for an additional little gold or any other reward.
I can do think of hundreds of these small quests and I bet you can all fill in with your own suggestions.
