I walked into ZA with a 3/5 guild group and no idea what was going to happen. We were punished brutally and it was the best damn heroic of my life. It felt like a little tiny raid all to ourselves. My non-guild group members (I'm not even going to call them Pugs!) were fantastic. Their numbers were average but they were patient and supportive and helpful, they provided input on what went wrong and then I ran it again as a healer this time and the Pugs were like that there too! We were all learning together and working together as a team. For the first time since Wrath started there wasn't an expectation for instant gratification just for simply showing up in the right gear!
It's hard, it'll get nerfed, we'll outgear it, tactics will become common knowledge and it'll just get easier again but I don't care because for the first time the community feels healthier and less negative. I don't know if it's just the new heroics or if Rift has finally sponged all the baddies away from this awesome game and they've finally gotten bored of calling for WoW's death because it's not casual enough for them anymore but this patch... for a patch that was so frowned upon from the moment it was announced... for a patch that was criticised before it was even on the PTR.. for a patch that was expected to signify the "death of world of warcraft"... may just be the greatest patch there has ever been.
And Firelands will be better.
