Change sphere for catapult

I think about map look and what you can change...i see few details but the 1st is sphere...look to much bad...change for catapult or something like that

I could see it being a catapult or something along those lines. Makes more sense and might have a cooler look, but I really like the sphere

Then is better to look like fire meteor stone...and map look to much like space 2166 year in future time...and heroes have some mytical look...soo map and heroee are two diferent worlds...

Well all the heroes are from like different worlds, and I guess the map is like a intergalactic battle arena so it kinda goes with the futuristic theme
