Remove Colour from Cover Rewards

PROBLEM
With the now abundance of 1* and 2* covers flooding the game from random rewards for completing matches, it's become increasingly easier for new players to progress despite the low chances overall of getting a specific cover of a specific colour from a drop or pull. For example, before this was instituted my OBW had no blue covers for over a month. Since it was instituted I've received enough OBW covers to remake her at least twice (along with every other 1* and 2* character).

Unfortunately, this does little for the players making the 2*-3* transition except dump a bit more ISO into their coffers which, while welcome, they can easily get anyways. Couple this with the fact that as more 3* characters are released, the overall odds of pulling a cover of the colour that you need goes down and it makes the 3* transition even harder.

SOLUTION
Remove colour from the cover rewards and allow the use to choose what colour they get for a received cover. This would only be for progression rewards, random drops, token pulls and event rewards that a feature an already released character. Event rewards that release a new character, like the recent release of Sentry, would stay the same forcing players to place well both individually and as an alliance to get all 3 new covers.
