Bahlak fight - how? (move speed issue)

So9, just curious how you guys are getting past Bahlak (the boss in Temple of Chaos turning into huge tornado)

I have 39% move speed in total, and still can't move away quickly enough when it turns into that huge tornado. Playing huntress with STR/DEX so blink is not an option really.

Any tips?

he does the chasing tornado move at either 75% or 50% health, so when you are close to those points you will see him sort of pause and 'wind up', thats when you run away to the edge of the arena, and then when the tornado begins chasing you, you run in a circle around the arena - you can escape it even with just 25% run speed (I used to do it on my sorc)
