New Wizard Types

I was just thinking of an idea off of the top of my head, maybe there should be different types of wizards. With the introduction of the ice wizard in Royale I was thinking the same idea can be applied to Clash of Clans. If there could be some way to have 4 different types of wizards (fire, ice, lightning, void) it would be cool. They can be separate units or a drop-down like menu to select what type of wizard you want, prior to training, each with their own perks. Fire would have the highest damage, ice would slow down enemy troops and/or defenses, the Lightning would move and attack fairly quickly, and void would have a lingering poison like effect. I have no stats or designs for these troops, I was just spitballing.
