Do you want alliance arenas to come back?
For those who don't know, Alliance arenas were arenas found alongside normal arenas. And they were pretty much the same, save for the fact that your entire alliance was working to earn points for a featured champion at a 100 million point milestone (about 3.4 mil doesn't sound so bad nowadays, does it?) This was early on in the game, around late May to August 2015. The last champion that was featured in an Alliance arena was Yellowjacket.
