I don't see why they can't just add a new AP/MS item if they want to, rather than removing Rylai's. Is Rylai's currently really a problematic item? For some champs I really enjoy using it if i need the health and the slow (Zyra, Malz, and Vlad, to name a few). I don't like that they're slimming down the number of items for AP champs. As a mid now, you go Zhonya's if you need armor/the active, Abyssal if you need MR/team magic penetration, and Rylai's if you need HP/slow... most of the other items are for pure offense and/or mana regeneration. There should be at least ONE item for each of these roles, I think.
