Been rocking Morde top lately. He seems to work excellently against champs like Riven and Renek right now and I end up farming up a storm because of it. Build him Tankaiser style.
Also, I cannot wait for the Skarner rework either. Everything I've seen of it looks great, but I'm still iffy on the E, thinking it needs a little wider range. Love that the AS buff is on his Q now though, makes jungle clearing faster with him than any other jungler I think.
I tend to suck with adc and I'm lucky I only play the role when friends. I tend to pick either Tristana or Twitch, but lately I've started developing "feelings" for Quinn and dominating with her. She can be a lot of fun.
