I'm curious as to everyone's thoughts on which heroes to bonus.

I've tended to select the newest 3* when they've come into tokens, which let me cover Hawkeye pretty much immediately. I've been hoarding tokens awaiting Star-Lord coming in. Once they're covered, I tend to select Dr Strange, Thanos (as my most used 3*s), and whoever I'm trying to get a 4* cover from (currently Thor, Captain Marvel).

For 4* I tend to choose whoever's close to 13 covers. Right now I have Coulson (12) and Carol (11). I'm curious if people often choose from the current 12 or opt to choose the vaulted 4* in an effort to get covers for them.

5* was OML, but is now Thanos as I hear good things about him.
