Now that everyone uses 1.8 i don't see the problem. Now everyone is at the same disadvantage, therefore it is completely fair. People whined about how the sprint key in 1.7 was ruining the game when it first came out, and now nobody wants to leave it. Just like everything else, MCGamer is constantly evolving and changing. We must leave some things behind to make room for the awesome new features of 1.8. The lag can be fixed by turning some settings down, installing optifine, and turning VBO on. Personally i find that i get better FPS with 1.8 than i ever did on 1.7.
