in October of 2009, our UI Team has been hard at work improving the visual components of the PvP.net interface. With the substantial renovations required to support Ranked Games, now seemed like the opportune time to give the game a facelift. We wanted the new look for League of Legends to be brighter, more visually appealing, and easier to use. I could elaborate further, but I think that once you get a look at the accompanying screenshots their work will stand on its own.
i hope some of the in game champ bugs are fixed
such as nunu ult not being visible when casted in brush (seriously how do can you not see a massive blizzard your standing in) and chogaths ult doesnt cast when standing on the enemy sometimes no matter how much you cast it.
