You'd rather they use Juggernaut instead of Blob in the Brotherhood? But the Brotherhood is essentially comic relief with the exceptions of Lance and Wanda (And now Quicksilver's finally becoming less of an annoying prat). I WAY prefer how they brought him in in Evolution as opposed to bringing him in early on like that.
Oh, and "The Toad, The Witch, and The Wardrobe" is a great episode. One of Evolution's best strengths is knowing how to use their characters so that they're all essentially competent in some way, even Toad and Blob.
