Location specific buffs
It would be cool (at least to me) to have buffs to champions based on the location of the fight
For instance if you are using daredevil in a fight
And the fight begins in the hell's kitchen region, DD would get a +20% increased stun duration buff
Magneto If he's in that aircraft arena would get a +10% increase in magnetite ability against metal opponents and 10% attack against non mental opponents
Thor, Loki,Angela and hela would get +30% in buff duration when fighting in Asgard
The avengers fighting in the avengers tower would gain +10% ability accuracy and +5% power gain
This could add more excitement to players knowing their champs would get buffed if theyre lucky enough to start the fight in the preferred arena
