I'm not into arena or ranked battlegrounds, but I love it when the Horde pay a visit to stormwind, and we go visit them for some payback. Its been happening a lot more since the change and I love it. And I'll tell you what - a lot of the others on the server are loving it too judging by the number of players getting involved.
I'm on a PvE server and it's other pve servers forming groups and raiding. I love it! I like my questing and the odd BG to relieve boredom or gain some fun xp but if it's red - it's dead. And that includes me.
