The Gold Arena
With the constant addition of new champs and the pace at which we have been acquiring 5*'s I think it's safe to say majority if the community is lacking in gold. So, in order to fill this void I would like to suggest a Gold Arena.
Every Sunday, in addition to the current puny crystal arena, an arena with only Gold milestones and rank rewards should be offered. This would allow the community to earn the gold we desperately need which will allow the game to continue to move forward all in a suitable fashion.
The community has been asking for a solution to the gold shortage for a while, I believe this would be a suitable fix.
