So starting today Kingpin, Hulkbuster, Carnage, Ant-Man, Thing are all available in The Vault. Good step forwards by the devs.
Now for the much more that can be done, like making 4* a Top 10 reward, a PVE progression reward, higher percentages in single tokens etc
I would luv to see more 4 
prizes in the vault; just take out a few 2
prizes. Maybe lower the 2
rate to like 50%. 
always been the same 3 in mine, starord, px, and IW… not that i ever pull any of them.. but has been the same 3 in every vault, even ID4 vault, just different covers each week.
There’s a Thing in my vault. That’s nice.
Making 4* a top 10 reward may be a bit much, but top 5 with an extra cover for first place should be doable IMO.
Wait, you have five 4*s in your vault? I’ve only got 3, still o.o
I need to go check my vault! 
I got a
from the vault today…you know that 1 cover out of all the others you DON’T need.
We need to start having better pull rate percentages on 4*. It is getting to be ridiculous how many 4* are in the game now yet the cover prices haven’t changed since the beginning. This is a HUGE turnoff to new incoming players as they are being locked out of in-game content unless they want to spend massive amounts of money!
