Spell Balance Suggestions

[AmazinPew]

Can Volcano Barrier be changed slightly? Currently it leaves you locked in place after the barrier ends, leaving you rather vulnerable. Compared to every other invulnerability though this is very awkward. Take it's close cousin, Sand Barrier. When it wears off, you can move instantly. Sand Barrier also has a shorter cooldown, and more damage. Could the lock time on Volcano barrier be removed?
