Again, i think the game is where it is now, the best teams in the long term will need to have 40k+ arenas. It's not fair to change that now for the teams that have pioneered to this level by adding an arena tax or putting a cap on revenue below the nearly 700k you can expect per game now (not including taxes). It's not fair to make the price of expansion greater for the teams that are starting later or trying to catch up.
But, BB's could put a cap on revenue or adjust the formula's now, or we might be having this same discussion in the future about 60 or 70k arenas.
