If I didn't keep running into pillars before I got out of range, the lightning attack probably wouldn't have caused as much damage as it has.
You could try toggling on and off lock-on? Turn the lock off while he's going for the attack before darting out then turn around and lock on again.
Sephiroth probably has a better tactic, most of mines revolve around the notion that you suck at the game.
