Seven starting heroes? Well... with all due respect, that's too much. Three would be enough, but no more. The map doesn't lag. In the starting battle, Cain lost on auto-battle. I'm trying it out now. I'll play tomorrow. But half of the heroes need to be removed.
The extra heroes can be placed in the Sanctuaries; there are many on the map. They won't interfere as errand-runners.
