Regarding your comment on the 6k vid, for the most part you're probably right, they aren't that useful. However... as a meaty attack in a clutch situation where your Eddie gauge has yet to fill up (maybe around 60% or so) id say it seems well worth to attempt. Eddie is all about meter management.
Don"t take my comment on the 2nd vid too seriously. If you really want to see what I actually consider something "crazy" would be something like this the first combo HERE. But hey I don't care since I didn't make it, messed up unblockables aside iI learned a few things tho.
