There are no good items to defend against this.
Brand AP teemo and akali was instakilling our teem in a game and it was the most hopeless I ever felt in league.

first id like to point out bad matches do happen. and there are quite a few good items vs ap banshee veil being the top i my eyes theres a whole section for magic resist. that as well build health. aps an only go so high and there cost for items is also high. who was in your team?

You lost because they had a lvl 3 Akali.

Ashe Skarner and Kass. I had banshee veil. It almost cut through the Mpen. merc treds and one other item... it's late sorry. I really could of used a FON though. The damage that they were dishing out was mind blowing for 3 item slots of MR and 2 HP.

In retrospect we probably would of been better off going pure damage, but it was just a bad match-up and we lose that one 95% of the time.

if it is a team full of ap, what is stopping you from building 6 mr items?

truth

a Darius with a black cleaver was literally 2 shotting all members of my team yesterday... so i guess it balances out?

Pshhh darius is op no questions asked
