Riot you need more item diversity

It would solve a load of balance issues.

If we had more actual HP regen focused items, it would deal with % hp damage.

If we had more anti regen items, Morello wouldn't be picked on near every mage.

If we had more actives for CC, then people like Katarina, Yi, LB, and Zed would be less of problems (talking about the feast of famine portion not necessarily OP or broken).

AD champs need more mana regen items. AP tanks need more item diversity other than the standard Liandy's, Rylia's, Abyssal, Rod of Ages, etc.

I feel like the game could be in a much better state if we just had more items to help give ways to interact differently each game. So every game isn't build X item and win. It should be "Hmm... Should I build X item or Y item to help myself more?"

I feel like just adding items would bring back champ diversity so much more and allow for new kinds of comps to be made so the game stops sitting in the stale spots it sits in when Riot isn't putting out broken items.
