Why are we earning roughly the same gold now than we were at launch? Blitz has become quite tedious specially with toons that no one is really excited for (daredevil, blademaster, gamora, quake, etc.). The cutoffs for "good" champions are increasing at a frightening speed. Personally I had 3 teams last month and was able to get around 2.5 mil consistently for top 1500, now I have 5 and get 3.5 consistently and by next month I will have 7 sure to win blitz teams. With increasingly high scores for rare toons and the frequent "easy to farm" toon blitz we need extra milestones or double blitz. The double blitz will work the same it did during the ironman event a very long time but they can have one of the blitz be for a "rare" toon and the other for an "easy" toon and that way new players can get the easy toon with lower cutoffs because most top end players will go for the rare toon. This solves the problem new players face when they enter the veteran bracket and contributes to rewarding players more gold for more time spent grinding.

TLDR: Get new milestones and have double blitz that helps everyone to make the game mode less boring.
