The key word here is optional guys - people are always so quick to jump in and nay-say because they feel that the particular thing being discussed doesn't sound as though something they would enjoy.

Something optional and as simple as this would only require a bump in the mobs level/speed so it wouldn't waste any of Yoshi and his teams time so there isn't really any reason to say no to something like this.

But .... to the OP - I would totally be up for things like this, always good to experience new challenges / have things to tide you over whilst waiting for fresh content.
