People in this thread are devaluing what a character can do with ADVANTAGE. All I read on that second page was "not punishable", "can only do a measly 2%", "way too safe", etc... This is MKX, you're punished for blocking against over half the cast.
Lets run through it a bit.
Tanya does 1 rekka, now -7 against Liu Kang. Liu Kang can punish this with F1 if frame perfect but "there's human error we're not gods". You're right, so normally a Liu Kang player is going to go right into F213 which between the block pressures, cancels, staggers, could be anywhere from 15% straight block damage to the entire round lost. Lets put Quan in his shoes now. How is he supposed to deal with the Rekkas? He can only D1 and it does a measly 2% damage?!!?!. Yeah but he gains frame advantage, providing him with a 50/50 if properly spaced, where if it hits she could possibly be dead. Even on block she could die because she'll have to guess a few more times after that. These are examples from the top tier characters, but I sure as shit don't want High Tech Jacqui or Reptile for example hitting my block either.
What I'm getting at is that this is MKX, where often times losing your frame advantage and being forced to block can be just as bad as being unsafe.
