You ever notice Riot's champ reworks come out a really poor times?
Most tanky supports are on the way out, mage botlanes are starting to take over.

Riot specifically makes changes to kill lane swaps and weaken the effect of splitpushing.

The early meta is of hardcore damage and fast junglers rather than "safe" junglers.

AD and Lethality are still pretty strong. Some teams run an AD mid and top?

Can't wait for the urgot rework when suddenly melee tops are the #1 pick and poor Urgot gets his wonderfully fugly face stomped in.
