More cover level information provided in-game.

Currently, the game only lets you know what the next cover ability level will grant you. But you have no idea what is coming in the following levels. This wouldn't be a problem if you were able to level all covers to their max, but currently you are not. So, it makes it impossible for an uninformed user to make an informed choice in what covers to seek out.

Example: (From Wolverine - X - force)

Recovery - Yellow 10 AP
Wolverine starts the process of regeneration. Creates a 5 turn Countdown tile that heals 420 damage, and another 42 for every yellow AP.
Level Upgrades

Level 2: Reduces countdown to 3 turns.
Level 3: +20% base heal.
Level 4: +40% base heal.
Level 5: +300% base heal. Increases countdown to 7.

That level 5 ability is such a leap (both in what it does and how it changes), that you can't possibly see it coming until you get to level 4. Which by then, you are too late to go back and revert him to level 3 if you wanted to.

The only way to gain this information is if you come to the forums and seek it out. It seems like it would be an easy add-in when you access a character through the roster they have individual pages dedicated to each ability.
