They wont pushblock because even without demon Darkseid can just fill the screen with a laser shot immediately and then they lost a bar and are still in the corner. This is also good if you want to reset them into unclashable damage. I dont understand why everyone is so eager to dismiss otg reset into full combo just because it is situational. Also in your scenario it is not a gaurunteed finish either because they can air escape out of the comboand potentially punish the whiffed stomp where as this keeps them fully grounded so they cannot.
Let's see, to fill the screen with laser you will have to spend a bar as Darkseid (you have said that you either don't have meter or don't want to spend it to end the round). So they spend a bar to get you off one of yours? Seems like an alright trade of to me.
If they air escape- they spend 2 bars and end up in the corner, they can only do it after the explosion, when you are jumping at them with j3xxStomp and their back to the corner. Don't wanna waste a bar to pushblock on a magic pixel but do want to waste 2 in a situation where you will just end up back in the combo?
Everyone is so eager to dismiss an otg reset into the restand because it can only restand a grounded opponent so only off a 13% combo.. in order to do it you open them up with the explody guy out, but you just do 13% into another potential pressure/mix instead instead of 30+% meterlessly which you can do without meter with the explody guy out. Very questionable decision ))))but I mean I am tired of trying to show you and the op that it isn't optimal to say the least, in the end of the day it is you way of playing the character. People online do even more stupid shit when they open you up, I guess I can't tell you not to do that)
But I am glad that some top players who saw this thread are asking the same questions I did.
