So, I recently started playing again...mainly to level up all the Avengers while they still have that XP boost on. I already had Thor and Iron Man at 60. I finished leveling up Hulk and took Captain Douchebag from 1-60. Now I'm leveling Hawkeye. I don't own Black Widow or Vision, so I did some random hero boxes, but didn't get either.
My question is what to do with the rest of these currencies. I have:
441 Eternity Splinters (I usually keep 600 on hand just in case I really, really want a certain hero I don't have yet.)
1185 Odin Marks
535 Cube Shards
1051 Cosmic Worldstones
925 ARMOR Drives
1590 SHIELD Omega Files
361 Hero's Commendations
6 Protector's Commendations
Is there something considered a must-have for all of those currencies? If it matters, Rogue used to be my main with usually Iron Man and Thing behind her for preference on who to play. Also have Ms. Marvel, Emma Frost, and Invisible Woman at 60 in addition to the Avengers I listed earlier. I haven't prestiged anyone yet.
