OP Champions

Why does Riot buff all the stupid champions that everyone hates to play against? Yi is pretty strong right now because people in low ELOs don't know what to do against him, and by the time figure out he's 7/0 and does more damage than your entire team while being the tankiest champ on the map. Xin got buffed for no reason at all. This dude is so binary that I don't even know why Riot would want people to play him.
I hear Katarina is getting buffed, which I can't say much about because it hasn't happened yet, but I'm pretty sure people don't miss getting insta killed by her. Kog'maw is in a pretty fucked up situation... I don't even fucking know what's going on with him, but i'll mention him here anyways. The Duskblade of Draktharr item is just fucking great. I love the concept of removing DFG and then adding this item a couple months later.

I'm just a bit frustrated with all these weird changes and I don't want this game to go downhill because I enjoy it a lot. I hope Riot will listen to some of the more well presented feedback on the boards and continue making this game better.
