Geezus..
This is a top 3 all-time defensive title from Midway/NRS alongside Injustice 1 and MK2. Even Injustice 1, which was marked for strong defensive archetypes (Aquaman, Black Adam, Sinestro, Martian, etc.) also had extremely offense-heavy ones (Bane, Flash, Doomsday etc).
You are going to want to have some kind of offense in every fighting game, and especially in an MK game. Without throws, etc, the meta would be extremely stagnant and the pacing glacial.
Also, flawless blocking is by nature an incredibly strong defensive mechanic.
Whatever this game is that you’re trying to turn MK11 into, it’s definitely not one that I’d like to play. Good lord.
