Thank goodness that hideous grind is over!
I managed to get the meta achieve on my main and 4 of my alts, the lowest of which was only level 40. I got a strider for each of my 7 characters as well. On the final day a strider dropped from an egg - on my lowest level character, naturally. By Saturday night I didn't figure it was worth the energy to run my lvl 37 to Un'Goro, and I didn't feel like harassing my guildies to show up with a blossoming branch, so I gave up on getting her the meta achieve (and she still hadn't found the pants from an egg) but both my lowbies managed the Chocoholic achieve. (So less work next year, assuming I'm still playing and they don't change the holiday.)
Farming the eggs was a nightmare. I've got BAD lag (not fixable - it's my satellite service, and they're the only game in town) so even when folks were far away and opening other eggs, they'd manage to make it over to my egg and steal it out from under me even when I'd clicked on it long before them. I tried running around for about a half hour on the first day. That netted me all of one or two eggs. Finally I gave up and camped. By the third day, things had lightened up enough so that I could run around again, and that definitely got me more eggs than camping.
Dolanar I didn't even bother with. Too hard to see the eggs, and with my lag I didn't have time to search for them. Azure Watch was busy but doable, and Kharanos was actually the quietest area (other than Dolanar). Goldshire was a disaster. Every single egg spawn had at least one camper, often more. That lasted right up to the end of Noblegarden.
What ticked me off the most about this holiday is that it became all about greed and beating out the next person, rather than having fun. I agree with the idea of spreading the eggs over an entire zone, or doing it the way Archaeology works. (Or both, since even if they're your own eggs, it would be more of an adventure to locate them across the whole zone.) The way it is now, it's more like a job than a game. Yes I realize I didn't NEED to get the strider mount on all my characters, and that I probably didn't need the meta on all of them either, but...hey I want my characters to have the nifty stuff even if they aren't my main.
That said, the one thing I WAS grateful for is the fact that this is the fist meta I could complete on my main since I came back to the game in October. She's only level 79 now. (I've been going slow because I only finally got Cata this past month.) So level 85 instances have been out, and thank GODS this one didn't have a PVP achieve, since with my lag I can't hope to PVP.
But on the whole, thumbs down. Bliz really needs to rethink this holiday. (And preferably rethink the other ones that insist on PVP, which I personally hated even back when I had decent internet.)
