I won’t bore you with my entire (not particularly exciting) roster, but I need a slot for an IM40 and Hulk cover.
I had to let a Black Loki, a Moonstone and a Mod. Hawkeye go some time ago and my current “worst” covers at the moment are a DD Blue, a 2 cover Mod. Hawkeye (with another 2 covers waiting) and a 2 cover Moonstone (with 2 covers waiting).
I am also due for a Heroic token and a Green Rag in a few days.
Sell DD, Moonstone and don’t keep Green Rag? I know MH is due for a change soon, but keep or not or sell only as a last resort?
You will definitely face a flood of hawkeye covers if you keep playing and will sell them by dozens. Nothing to save there. Moonstone is also easy to recover and can’t recall a situation she could be missed. Rags is for keeps definitely. DD is IMO an useless character, still a *** and may be required in some battles.
In general keep in mind that *** is hard to recover and recent changes suggest it will be more like that. ** covers you get from ubuquitious heroic tokens every event drop at least one, and about every 6th gray token that grows on trees.
Those don’t sound like bad choices, but I’d say it’s hard to give proper advice without a roster list. Could be worth holding on to the 3-stars, even if they’re not the best you never quite know what you end up being able to build.
Make sure you farmed all the HP out of the prologue. There’s quite a lot in there. I thought I would have to ditch characters also, but between the prologue, Brotherhood, Hulk, and various PVPs, I’ve managed to keep up with my slot needs and not had to delete anyone.
