The industrious folks at Wowhead News and MMO-Champion are busy datamining away at the PTR, as patch 4.3 has just hit the servers. Lots of interesting class changes (death knights, you done got a ton, as did shaman) and holiday achievements.

Just breezing over them at a first glance, we can see that there are tooltip changes galore, including a distressing change to Enrage for us fury warriors (bleeds look to be excluded from Enrage now, as it now states physical damage instead of all damage). Holiday companions that used to require a reagent now just work during their holiday, like the Winter Reindeer. That's a nice change, in my opinion.

We'll be bringing you the best of the patch 4.3 PTR changes all night long, so keep an eye on the site.

Brace yourselves for what could be some of most exciting updates to the game recently with patch 4.3. Look at what's ahead: new item storage options, cross-realm raiding, cosmetic armor skinning and your chance to battle the mighty Deathwing -- from astride his back!
