This is not a Shocker issue but an issue with the nodes on this path. It took me 4 of my 5 champs to get through Shocker, but the same thing happened with Prof X as well.
What is happening is the first time you knock down the champion the Immunity to Armor Break goes on cool down as it should. After roughly 10 seconds, the Immunity returns and can no longer be removed. The champions then start gaining their Armors and Unblockables and become virtually unstoppable since they are also taking less damage since they do not have any Armor Breaks on them.
I really wanted to 100% 9.2 before 9.3 comes out in a week, this was a big bummer to discover today.
Not quite. While knocking them down removes the immunity, knocking them down AGAIN not only returns the immunity, but keeps the cooldown. While the cooldown remains, the immunity cannot be removed again, and every knockdown refreshes the cooldown.
Interestingly, a similar node is in 9.2.6 for nullify immunity, removed by heavy knockdown, multiple heavy knockdowns do NOT cause the same behaviour.
I followed the instructions in MCOC noob video and got wrecked, my whole cosmic team multiple times. I took the scurge path instead, sp.ham n jack olantern was MVPs on that path, and onslaught vs karnack. I hate i wasted revives on the armor break path tho
