TL;DR:
All but 2 2*;s champed (moonstone and johnny storm)
9 3*'s champed with 3 ready to go once I get the iso
Scattered 4* covers, with Medusa, Carol and Gwenpool with the most at 5
I just rostered Luke Cage 4* (black) since he was essential for the latest event. Now I have ~900 HP and Iron Fist 4* (blue) about to expire. Do I bother rostering him? I hear he is not great.
Also, in general, when I get 4*'s should I prioritize rostering them at this point (even though they are borderline useless at 1 cover) or continue adding 3*'s and sell off the 4’s if I don’t have the HP? I have a bunch of 3’s in my queue that are not in packs anymore and they just don’t seem worth it.
Uh, Hulkbuster is vaulted - so if you sell him now, then you likely won’t see him again until he’s a required character in a future PvE. That means no burrito for you either.
And when he is an essential character, you will also have to do an optimal day 1 clear without him (7x per node) to make up for missing his essential node if you want to reach progression. Plus you’ll have to have the HP on hand to re-roster him right away for the rest of the event.
Sell a 2* instead - they’re easy to reacquire. You should be rotating them once they’re max champed anyway, so it won’t slow you down much.
