Kalista nerfs hurt her toplane early levels which lets enemy top survive easier early on which makes her drop a lot in strength.
Sett nerfs doesnt do much.
Maokai still best tank in the game.
Urgot recent buffs helps him a lot and is a great pick into GP.
MU Dependant = Matchup dependant, so champions that are impossible to rate without being in a good matchup, for example fiora is s+ in some cases, but otherwise C etc.
best blind pick tops: Maokai, Gp, Renekton, Wu, Sett
