We need Arenas back

@LuxorFPSFor me I paid very close attention to arena in general. I kept up with how many people played the ranked version of it which is a decent indication of how many people play arena.

So each season there would only have 18k people sometimes who have played ranked in arena. Last season had 6.8m who had played BR ranked enough to make it out of participation matches. I ignore rookie ranks in both modes as that could indicate that they played placement and then did not try it again or they are still in the participation phase. 

For me, I look at that like it was a game mode for about 0.3% of the population give or take.
