Tournament Idea.
I just wish Kabam could use this as an incentive to bring more people into the player base (and bring oldies back);
By holding champion idea tournaments. These would allow people to write up sketches of either new champions or old ones and put to a vote which one of what class was the most interesting/ excitable, and Kabam would either rework that champ, or build the new one according to those sketches. And the winner, and a few invited players, can test out those ideas/ mechanics before initial release. (And possibly have that champ as a 5*? that last bit was a stretch lol)
Btw, the sketches I'm referring to would be similar to what Bodhizen and I have done in champion improvement suggestions.
