Well, MYM has a certain ID in their system. If they are going to change the name, the name will also be changed for the previous wars/matches back in 2008 etc etc.

They would need to replace the MYM ID with a new ID (EG), but only for this tournament. For the next tournament they can enter the new EG ID to the grid : >

i see , thanks

lol so if thats true future could revive his 2 heroes and still have advantage

Yeah and if Grubby typed Whosyourdaddy he won instantly...
It takes time to revive 2 heroes? Yes you can get them at taverns, saves time cost's more gold and you revive them with half hp and no mana.
Grubby already outmicro-ed Future in the fights while he had less food/units.
His BM en SH were still alive, and just gotten stronger from the experience they got from killing his 2 heroes.
Im pretty sure it then would have come to the same rotation as it went before.

Just check my comment a few lines higher : )
