I had some luck against the Carnage/Venom/goon nodes using 3* Carol, Miles, and KK, and by luck I mean that KK was dead and the other two both had less than 2000 health left by the end. But the idea was to have Carol tank as often as possible to build up red for Miles to stun Carnage whenever the enemy had 7+ red AP (and recover some health at the same time), and downing Carnage I think is simple enough; the trick is to deny yellow/green to minimize the damage that Venom does you.
Oddly enough, KK, Psylocke, Hood destroyed that node.. kept stealing red and making strikes, by the time carnage died, i was doing 3k+ per turn, and her cheap skills kept KK healing. Manipulation team up ended venom.
I haven’t failed a node clearance in months and months, I just had to buy health packs to clear this one. Red feeder carnage nodes are truly unfair, and there’s 4 of them! Not right. I have never bought health packs before this event, I’ve bought at least 20 this time, only because I’m on the verge of T5. Won’t be playing this one next time
After fighting this for days, getting the LT, I got a star-lord for it. Gee, thanks, D3. 
I had just bought their bonus coin pack thing as I was feeling generous as well. What an insult.
this pve reminded me to go full sandbox mode.
dude everyone in my bracket WHAT HAPPENED it was so freaking close.. got up at 3am to make sure that i kept my lead and put up pts. Then go up again at 7am to push my lead out thinking okay theyw ill start playing at 9 or 10,but nope … won it by 8,000pts
Does anyone know what the build for She- Hulk was for this event when she’s required?
I recall I checked and she was 5/3/5.
