I sold a blue Hood very early on - I needed the space, and he actually gave my the last 25 HP I needed to expand a roster space. I was annoyed at one point I had done that because he was one of the last 3*s I didn’t have for ages, and then stuck at 1 cover for ages. Now he’s at 3/5/3, and I think I may have sold another blue due to having it maxed.
I think the first I sold due to having too many was either a Patch green or a Punisher Black - both prior to respec being implemented.
I sold a Black Widow Gray Suit early on, because I was confused by the 4 version of Black Widow, and I didn’t have the roster space. If it said Widow, I sold it.
I actually had this happen for the first time recently, sold a Black Punisher, it was my 6th.
Funny related story, when I started playing about 2.5 months ago, one of my first tokens (i think it was a heroic, but could have been a standard) netted me a blue C Mags. At the time I only had like 4-5 roster spots. A 1 blue C Mags is pretty weak, but since he was a 3 star i obviously gave him a roster spot. I used him quite a bit in the early prologue since he started at lvl 15 which was better than most of my team at the time. Well a week or two later, I built up a bunch of 1 star covers that were about to expire (ie.Juggs, Venom). I was debating between giving up my Bagman or Mags to make space. Bagman had more covers so I almost kept him. This was before I was on the forums. Thank god, I axed the bagman and kept mags.
Ditto. Wasn’t a fan of the villains early on. Although I learned how overpowered Rags was but could never get any of his covers. Still don’t have him fully covered.
I sold a Magneto and OBWs due to roster space back in November. This was before I was spending money on Hero Points (not that I spend much now), discovering the forums, and realizing I could have sold my unleveled Venom and Juggernaut for space.
I think I sold a (color unsure) Rags when I was only a week or two into the game due to roster space. I had a bunch of new guys in the queue and I knew I wouldn’t use him soon plus the extra HP was useful to open up another roster spot. Don’t really regret it since I still don’t really have the roster space, although he’s one of the only 3*s I don’t have.
The first one I sold was a yellow Hood, due to lack of roster space… which my 4/4/5 Hood regrets me doing. It’s also the only 3* I’ve sold since then for reasons other than having 5 of a cover/being cover maxed - definitely learned my lesson!
Black Punisher because I’d maxed it (since the respec became available I’ve then unmaxed black as I’m trying to max green). Followed closely by not 1 but 2 black Lokis because I’d maxed it (the first of those before I’d even pulled a single purple Loki) and after today’s Fearless Defenders awards a green Hulk because I’ve maxed that. I think that’s it so far.
