I'd like to start by saying that I play a lot 3v3, both ranked and normal. Something that has become a problem ever since the map change though is the removal of Thornmail from the shop. I honestly don't know why it was removed but it really needs to be put back in. It allows people to play AD Yi and AD Tryndamere and essentially 3v1 a team by mid game because of the way the champs kits work. Randuin's is somewhat effective against Trynd, but it might as well not have passives against Yi. Thornmail is needed so you can effective counter-build certain champs, including this above two.
I'll probably catch a lot of flack, but I don't care. Something needs to be done about this problem. Thanks for reading.
