Alpha Dragon

An immortal hero troop that is stronger than normal dragons. It can be obtained only from a single-player quest unlocked from the beginning. It moves and attacks like a normal dragon, except with more damage, health, and a special ability. When ability is activated, the alpha dragon will fly in a small circle and damage every building in the circle for the duration of the ability. It will also boost any air units with effects similar to those of rage spell.

Heck, even one dragon can do a lot of damage. Honestly, to op.

I think people just use OP as an excuse to not make the game way cooler. I garuntee I'd be getting that dragon and the invisibility spell.
