Please, for the love of Pete, don’t ever do a 7-day event with Carnage as a featured character ever again.
I did not sign up to play Marvel Health Pack Management Quest… 
It’s not so bad if you’re like me and have 100+ characters. So a few of them die. Not a big deal. You can even use some really bad ones and then just use Carnage Red the whole time.
Just bring JG and SW (assuming you have them).. all is well
Only two days left! And I already hit the progression goal so 2 more days of that just to try to place! 
I hate myself for wanting a 13th Jean Grey cover right now.
Partnering him with a couple of healers worked fine for me, X-23 plus Daken/Patch/Oml meant I didn’t use any health packs on those nodes in the entire event.
