Warlock >070 Spell Spamming

[Doubleerror]

I found a nice little bug in the Warlock-Maps (Warlockhomepage)...
In this Map you try to kill the other warlocks with your spells either with throwing them into lava (spells have knockback) or well till they have no hp left...

I hope this is the right section...
It started with the fact that I sometimes had no cooldowns even after casting a spell.
So I tried to find out what was the cause of this. And I always evaded spells from other warlocks just by stopping my warlock to move. Well the trick is pretty easy. After you use a spell like Fireball (Hotkey G) and click with the mouse to tell him in which direction it should be cast, you (needs a little timing - Too early = doesn't cast - Too late = you get the CD) press the hotkey for "Stop" (S in most cases) or "Hold Position" (H in most cases) and your warlock casts the spell, stops the cast after the Fireball was shot and you still have the spell ready.

This doesnt work for:

All Warlock Maps after version 070
The Spells Thrust/Teleport/Meteor/Windwalk/Furious Strike/The Spell with Hotkey "F" forgot the name...
