Would it be possible to have the option to use water elemental's freeze as a pull unless on cooldown? I have been having great success using the freeze ability, but would be even better as a pull so the target is frozen at the furthest distance possible. I was also pondering the idea of using blink instead of kiting after frost nova is applied(when being melee'd). Again to put as much distance as possible in between you and a melee target. The only problem with blink is, it would launch you off cliffs or into mobs. So I suppose a plug-in would be needed to make you blink in the direction you entered the combat from, or something crazy like that.
Also, there is a glyph that allows Evocation to heal target, was thinking maybe that could be used when not on cd, as its quicker than eating.
Anyway just some wild ideas.
