I stopped exploring Act 4 (was at 100% Chapter 2 round 1) and only got back on it due to the current energy reduction to two per tile.
It was very difficult to find general strategy and tips and majority of the help requests focused on the very tough nodes (e.g. Magneto 4.2.6, Juggernaut 4.3.3, Venom and of course big bad boss Maestro). I tried going back to the old forum and only managed to retrieve a few threads.
I also could not find information on the changes made to Act 4 after the v12 patch and whether there was any subsequent update.
I believe there are still certain sections of Summoners like me who would like to have a bit more information on Act 4 in general.
Veterans
As for the veterans who are already on Act 5, help to complete Act is really very much appreciated. Just please bear with us who don't have the Guillotine, Scarlet Witch, Wolverine, Star-Lord etc etc. We really need an alternative strategy.
Would be helpful too not to suggest
exploit like restarting game to get heal block on Magneto. It's an easy get around but somewhat kills the satisfaction of doing it the
correct way.
So here goes what I found.
