Right now, I have a roster of 27 characters with no duplicates. Do I have them all? Trying to determine my need for roster slots before blowing all my Hero Points on more covers 
yup, so far that’s all of them
Hooray, now I can start spending all my Hero Points on extra Thor and Hawkeye (Modern) covers!
Yea, that seems to be the best use of hero points. targeted covers for useful characters.
Eventually, I see buying powers directly being more useful than buying random covers, but I’m still missing enough first covers that the cover packs still make sense.
Not when you consider that 8/10 of those pulls are going to be 2 star characters and many those two star characters are pretty weak.
Better to just use the heroic tokens to “get lucky”, then use those hard earned HP?
Personally I’d like to have all characters with at least 1 in each skill, and preferably I’d like all 2* and below to have 13 skill points (and 3* too but I think that is currently out of my reach). So until then, heroic tokens are still a good gamble for me - I think only 6 of the possible covers are useless to me (both of Daken’s, two of Thor’s, two of C.Storm’s).
And all of Bag Man’s.
lol
Poor Bag Man.
