The most recent patch has given us a brand new Master Yi and some much needed changes as well as quality of life enhancements to the game.

It's been hell to restrict the laners from beginning with an advantage due to the early jungle spawns, a long-standing issue that has finally been fixed once and for all.  Lots of fixes that were imminent to happen and have finally come to light such as Ryze filling his bruiser role with ranged nerfs and Vayne becoming a little less out of control with cooldown nerfs and more.

Additionally, with the removal of Runic Bulwark, some fancy magic resist alternatives have come into play in this patch.  See the full details below.
