I am 100% fine with mord going to bot lane, the only way he could have stayed mid or top is if they destroyed his identity as a champion, besides a strategic non adc bot laner makes good solid sense, and gives a counter to your allied vayne, quin top.
Ok so you did not read the darius changes or only skimmed them, shame on you! now go take out your reading glasses and read very slowly.
Again you probably didn't read the changes to garen if you think this is the case.
Personally i don't get the rage about skarners change, he gains total AND bonus AD scaling on Q now, his shield now scales off of %hp which he builds lots of, ooh also he now effectively has a one click stun and his shrines make early invades vs him a really bad idea which is one of his major weaknesses, oh also if you retake a shrine it gives you 15 gold so hush about that.
Raw power is why they could not be strong in the first place, when darius had it he was pick or ban, same with garen, skarner, and morde.
