One thing that I think that would help you is if you go to the main fight screen, on the far right is a tab called training grounds. It'll teach you the fundamentals of parrying. That will severely help your game. Once you figure out parrying, parry heavy will be the easiest way for you to build up Hercules 12 feats of strength which will make him much harder. There is a quicker way where if you do just a medium light it'll infuriate the defender where they will be more aggressive and you can build feats by intercepting, but there is a learning curve. Secondly, watch the defenders power bar, you tend to push them to an SP3 frequently. Third, Hulk busters specials are unblockable, so if you are in a tight spot, fire it off. Forth, medium light mediums for the Pig. Builds power stings (porker poppers) a lot quicker. When the defender throws a special they take damage (the more they have on them the bigger it is) plus hams special 1 will make the AI more likely to throw the special. One thing I will say is at least you look at the nodes, not everyone does, so good on you for that. Some good content to watch is mcoc noob and Dork Lessons. They will help you.
Act 6 is lot harder than act 7 and more time consuming, .. seeing the play, i believe you need more practice in parry, bait special (dont hold block) if you want to bait and then dex or block it immediately when they special.. play event quest and low acts and practice more.. when you confident and do more solo's , only then start act 6..Bcoz all the local nodes are crazy for each chapter and its crazy..
I would have ranked up Spider-Ham and the trick to him is medium light medium combos to stack porker poppers also rank up your 5* Hulkling he's really good
Im so proud of your act 6 run. Especially considering you went down the hardest path. I was praying you wouldn't go down the void path when you were at that junction. You can get much further on a different path.
