New arenas

I think that there should be some more arenas. I have been thinking about what these arenas should be and have come up with the following:
1) One v One arenas in the same format as hero battles (stuff on the hero tab, world tournament, etc.)
2) Pair arenas in the same format as hero battles except that you always have to be in the same pair until you lose in rated game and your score is rated on your biggest win streak and your fastest win, etc.
3) Everytime you win an arena match,you gain some sort of token that can be exchanged for money (at an exchange rate of 1 gold to 2 tokens). But the tokens can also be exchanged at the Priests of Balthazar instead of balthazar faction at a rate of (5 faction for 1 token). The amount of tokens you win in the arenas depends on how highly rated the game is.
4) There should be a one v all arena wiith ten different people who are all against eachother, and there should be a pair variant of that also.

I liked the pair arena, because its a little sad to play HB alone.
But they could make the HA acessible to a group full of heroes.

And the random 10x10 arena
