The much awaited patch 2.2 seems to be on its way in just a few hours. The Public Test Realms have closed down and server maintenance started early. Those are the signs of a new patch. Patch 2.2 is known for the voice chat patch wherein select realms will allow their players to really hear other people's voices. Programs like Ventrilo and Teamspeak will not be the only venues to hear our WoW friends' voices now! 2.2 is also known for the option to report people who AFK in battlegrounds - a much needed and awaited option.
Here is a link to the most recent PTR patch notes. As we all know, nothing is final until the patch is released but here's to have an idea. Here are the other entries I find quite interesting:
General
Aww. Them troll mages and shaman would hate that berserk nerf but good thing pets are feeling the love.
PvP
Oooh. More love for people who play in smaller arena teams like myself.
Paladins
About time!
World Environment
The buff for the old world factions isn't really big but for those people who are leveling up and want to get some stuff from these guys, it's a nice to know it's going to be easier to get rep. The better news is that we finally get loot from killing those annoying monstrous kaliri. At some point there's no escaping them so it should at least be some reward for showing them who's boss. Good news!
There are other entries I did not list but as I said I only featured the ones I thought were interesting. What entries do you find interesting?
