The problem is that arena mode for 7WD is always without expansions because the Gurus witch are voting for it are the one playing without the expansion. And the way it is can never changer because expansion players can only become Guru by playing without expansion witch they obviously won't do.
That's a problem.
A LOT of player would love to play arena mode with both expansions (and top players in all time ranking are mostly playing with Agora et Pantheon), so there is two solutions :
-Alternate arena season from vanilla to both expansions.
-Create a second arena for 7WD with both expansion.
