What was the reasoning behind axing spell X (lockdown, mind control etc)?
As mentioned above in question 2, much like with units, we are also testing several new abilities for StarCraft II. If these abilities do not work as we would intend, it is always possible for a reintroduction of original abilities from the original StarCraft. We are constantly striving to improve and complement what has already been very successful with StarCraft for StarCraft II.
