Yes pro elves are slightly weak. They would be much improved with 4 blitzers and 2 catchers on the roster. Their offense is nigh-unstoppable, but so is any elf team when well coached. Their defense is probably the weakest of all the elven teams. They do have a strong potential for ball-holding strategy if you use doubles for dump-off on your catchers....but at AV 7 this can be a bit counter-productive. The only teams you should really need to hold the ball against are skaven and certain other elf teams anyway.
