Irelia, Swain, Chogath, and the rest of top lane is too buffed. Midlaners can't play top in the long run. But top laning melee have such large healing and shield mechanics that mid laners can't go toe to toe with them in Mid either.
Additionally, the new "negate" shield and healing mechanic makes no sense since you did not give it as an ITEM buff, instead you gave it to top laners.
Meanwhile for midlaners, its a serious issue.
