Shocker

Animation lock?

You know how moving while casting cancels your spell? In 1.x you just couldn't move while you were casting. AoEs you have to dodge weren't as omnipresent as they are in 2.0, but there were still a lot of boss fights you had to be very careful when you cast or else you'd be locked in place while an AoE came in to bash your brains out. In the hard Ifrit fight after the first stage, you had to wait until Ifrit had just done a special move to cast, and then you'd only cast one spell, because that's how long the safety window was. He spammed those special moves, so you had a lot of opportunities to cast, but you had to do it at the right point.
