Yesterday, I was playing with one of my friends, and helping her along in Azteca. I noticed that she kept getting a critical, and the monsters kept getting a critical block. When a boss got a critical, she didn't get a critical block. I think it is kind of unfair that most monsters either have a 0% critical block or an 100% critical block. They should get different percentages just like us.
I also noticed how when I got defeated one round, the same round all three other monsters attacked my friend. Its like they were changing their spells mid-round. Is this possible to change?
