Dees should be more aggresive. They should pounce every chance possible. Same for the Doos.
Speed up the Dee's animation. Give more KB to their attacks as well.
Rather than take out the Dees. Make them actually useful.
This is the problem with Dees I have. they are practically useless compared to doos and serve really no purpose that a doo can not fulfill.
Either take them out or improve them.
