Idea for huge maps

this is a crazy idea but i will stil suggest it.
what if there where huge maps. you get 8 keys a turn and you can use a total off 56 keys in 1 game.

I think this can be good and bad at the same time, good cauz this would be great fights and for pro like hopeloy this would be (in my opinion) epic fights to do, and bad because the fights can be long and phobies who only move 2 or 1 will be bad for this maps
