So I have 10 4* covers in the queue for potential Champions. Running out of time on a few, and also trying to rebuild the 2* farm (only 4 are champed right now). Any advice for who to try to champ next would be helpful (or even advice to respec).

Here's what I have:
icon_carnage.png at 175, (3/5/5). greenflag.png and redflag.png covers in queue.
icon_elektra.png at 220 (3/5/5). 2 purpleflag.png in queue.
icon_starlord.png at 175 (5/5/3). redflag.png and yellowflag.png in queue.
icon_hulkcho.png at 140 (5/3/5). 2 blackflag.png and 1 blue.
icon_professorx.png at 141 (5/4/4) 1 purpleflag.png in queue.

I am pretty much ISO-starved, I'm about 500 xp from my next level (80), and 7 covers away from maxing my next 2 star champ. I'm thinking to go for Cho or Starlord, but they are quite far from 270. Elektra is the closest, but not really who I want to champ next.

Are any worth a respec? Should I sell all and cut my losses (and not pull anymore LTs until I get who I want up to 270)? Any advice would be welcome.

Thanks in advance!
