I agree with a previous posting that Arena formats are unlikely to change much if they are driven by the people who already play them a lot as they like that format; the people who have little interest in the current format would not play and so would not gain the chance to vote and change them.
To combat this, would it be possible for games with multiple extensions/variants to have two Arenas: one for the base game and one for different extensions/variants? This would allow the purists to maintain their base game, and people that like extensions/variants to vote on which extensions they want each season.
