Lasereth, in such a short time your analysis has improved immensely o_O. I wonder how far down the metagame trickles and how fast ;o.
I'm also glad you're current on the changes they are doing to combat this new metagame. Yi is still viable, just you really need to construct a team around him.
Also, I'm not a huge fan of 5v5 gank squad so my friends and I try to avoid it as well. I'm down for 3v3 TT if you are especially, that's my favorite map.
@Ironpham: Hahahahahahaha hahahahahahahahaha ha. Heimerdinger. xD.
If you haven't played in a while, you might've missed the nerf to him. He's pretty much the only hero I don't consider viable right now.

. I liked him too, it was a shame. Personally I think he needs to be reworked, he affects the metagame very negatively.
