You're 'stuck' because you're character is doing an action and it makes sense for get punked my eruption if you haven't recovered from an action in time. Instead of changing animation lock what they should do is improve graphic cues so you don't think 'wow I ran and am out of eruption range while still doing doomspike, why am I hit?' Swing the pendulum the other way. I say, work on that instead. The hardest thing about Ifrit isn't 'AL' it's plumes in my opinion.
