Who to upgrade for act 6 overall

moonslayer

I just completed act 5 and thought about heading towards act 6 but got my a** beat the first fight and I really don't have the most optimal teams and I don't really have a lot of gold so i need some suggestion on who to wisely spend my gold on upgrading
Any help would be much appreciated
Thanks.

Doctor Doom and if you can awaken Nick Fury he is also insane too

I am in the same boat with my mini acct. I forgot the big difference between act 5 and 6 until I got there with the mini acct.

Doom is a killer, awakened fury is a killer, Venom is just a beast, especially with the venom relic.

I honestly forget what counters and such you need for act 6 cav push, it's been a longgggggg time for me.
