I withhold judgment until this plays out in game, but I have two major concerns reading it:
1) Did CM get enough of a nerf. It looks pretty good. Reduce AP so takes longer to get the really high damage. Reduced range so you are a bit safer when on the other side of a creep wave at the game start. And increased cool down so now you are only dodging it every 5 seconds instead of every 4. My base thought is this is a good testing point to see how things go, they can always adjust more if he is still a monster.
2) Trist untouched. I am not sure what they think in these notes are going to counter her, but the little tank with massive DPS and more escapes than Houdini sure seemed in line for a major slapdown late game to me.
Oh well I suck anyway, so I am not guessing any of this is going to affect me too much. I will still be way upside down in deaths to kills.
