as for the witches i know they cost the earth.....but jump up dodge and eventualy block makes a killer runner add frenzy and they can push people around with reckless abandon!!
i think the darkelves sit in a funny niche of there own in bb. they are neither a running team or a passing team so i think a nice split of players makes more sence.. and as i said earlyer i think at least one witch should be in the team just to make it a dark elf squad, instead of a dark painted highelf squad

also witches DO draw alot of attention from running teams who love to spend the game chasing a lady round the pitch in the hope of stamping on her!!

edit: thanks for all the input guys
