Just can't wait to see how the new talents system pans out in Mists Of Pandaria? Like, to the extent where you need a browser-based calculator to play around with them ahead of time?
Well, I can relate, so knock yourself out. Blizzard's Mists Of Pandaria talent calculator is actually very robust and makes for an entertaining diversion as well as a way of planning your builds. The new streamlined system replaces dozens of weaker talents with a handful of more powerful options, which should make the experience much more engaging.
