So I have several older 4* that I can champ but have been waiting on - Nick Fury, XWolv, and Invisible Woman. I can also get a Flaptain cover relatively easy and champ him but I don’t see the need for that now. I am sitting on about 1,700,000 iso and I have several older 4* close to 13 covers (I need to update my sig later today as I opened a hoard of covers at the start of this season). The only new characters that I am close to 13 covers for is Gwenpool and Coulson.
My strategy is to keep enough iso for Gwenpool as I think she rotates out of tokens next (or very soon). Coulson can wait since he has a long time to go. Of my older 4*, I am two covers away from Iceman, one cover away for 4* Cyclops and 1 cover away from X-23. The first two I will buy from heroes for hire since it is the easiest way to get the specific covers I need as opposed to bonus heroes. X-23, I will get her last cover from shield supply within the next month. All three are at level 188 and require 270,000 iso each to champ approx. (not counting 10,000 iso champ cost I think). The only other vaulted characters I am working on atm are Moon Knight and Peggy through bonus heroes but neither one has more than 9 covers at this point, so still a ways off.
My question is, are any of the older 4* I listed above (Fury, XWolv, IW, or Flaptain) worth putting iso in to champ at this point for me? I am basically a PvE player only. I love Fury’s blue against active AI opponents and his other powers are meh. XWolv’s Black is awesome and his yellow healing power is ok but he is such a glass cannon. IW seems way better than she used to be as well but don’t know how well she is for PvE. I waver on Flaptain only because he is slow and I will already have a lot of (Blue/Yellow/Red) heroes since I have 4Thor champed, will soon have 4* Cyclops and am working on Peggy. I could probably have enough spare iso to champ one or two of the above and still have a reserve for Gwenpool, should I get the covers I need for her. The next closest 4* in the cycle for me to champ I believe is Riri (maybe 8 or 9 covers now) and I don’t know if she is worth it either.
Advice?
