Stance or Blast please help! Alright everyone i need help deciding on a very hard choice. Right now i have about 23 sp in blast and 1 in Stance. I would like to kill Bigfoot faster as soon as possible. Here's where the problem comes in, i can kill bf faster with a higher success level of Stance because i get to hit it 2 times faster when it stomps, BUT if i raise Blast first, i can hit it with higher damage which also means i can kill it faster as well. So what should i choose to do first? Remember that i like to kill BF a lot for the mesos.
