A drop of bleach
I’m so glad you’re going to make the Colosseum—which, let’s face it, is by far the best game mode-the centerpiece of your game. A mode that prevents you from using your characters effectively, since the bosses don’t trigger the abilities of most characters-it’s always the same four, those four unbearable ones-where you’re stuck using incomplete teams without their ultimate abilities, turning this into a game of chess with nothing but pawns, and it’s by far the most monetized mode, managing to monetize its own monetization. As for tweaking the arena matchups-or tweaking any of the game modes released back in the Pleistocene-you can do that when you’re not busy asking for another R10 for your new Legend.
And not to mention that in training mode they only let you use your own characters-okay, fine-but the fact that they don't let you use the Omicrons is... Well, just what I expected. Nothing.
That said, the 500 crystal pack is cool, and so are the extra fragments you're giving out for the Colosseum characters. Though a drop of bleach won’t clean out a dunghill.
