You guys just can't grasp the concept of reskinning.
Reskinning is making one enemy that functions like another but [i]looks[/i] different. EG: Spider mines are reskinned Oracles.
The Taken [i]function[/i] differently from their parent entities. They look the same, that's kind of the point. You could call them lazy design at best, but I actually like the concept. Magical space zombies.
