I know some people are saying the game feels a little stagnant and all the mirror matches are getting a little old. I have an idea to make things fun and fresh so hear me out.
There should be a new arena called "Mixed Arena" and here are the rules.
The leader can't be any of the top 10 leaders in squad arena and you can only have 2 toons of the same faction/tag. This way it gives people a chance to get creative with with the squad they put together and won't have to face constant mirror matches. There are so many leadership abilities that are never used (many of them never will be even after this) and this would give even advanced players ways to explore new concepts and compositions.
As far as rewards go maybe it's only half of what squad arena is. I understand the game needs to make money and though people may or may not spend money through this "mixed arena" (although it will give us a reason put more resources into characters we never messed with before) it will keep people in the game and bring new players in as well who will then perhaps spend more. At least it will raise moral and add some longevity to the game since this would constantly be changing.
Anyway I think it would be fun.
