LOL, ya right, ok how about your Cataclysm Day 2 plans? Well I have some observations that may change what you do.

1. The beginning zones for leveling to 85 for Cata has some SERIOUSLY awful quests. MH has a few that are just stupid tedious:
A. Looking at ground for parts of a staff that have a long respawn and a really really small glitter animation next to a glittery river! AWESOMEx5! Oh and you need to pick up 8 of them. OH YAY!!!
B. Target a fire spawn and use item then AOE the adds down. Sounds simple right? Welp, no not really. Respawn is nowhere near what it needs to be to handle the influx of players ( this area screams PvP all out war and ganking) and there are only a few spawn points.
C. I found a lot of collection quests in MH, one so annoying I had to take a break halfway through (click the cute fuzzy squirrels before they dodge your mouse click. SO MUCH FUN!)
These two quests are just the ones I remember off the top of my head. Some parts of it is fixable and some is not. Overall I think the quest hub ideas is neat, but it guarantees that everyone will be in the same area come server respawn. Also it makes the zones seem really small, even though they are not.

What I suggest for those of you boxing alliance side: Level a worgen team with heirloom gear. There is a bunch of easy quests and very few collection quests for a long while. I can't speak for goblins, because I havent leveled one yet. Also make sure you use a class that has instant cast spells/abilities because everywhere will be a gankfest.

Once I level a team of worgens for a week or so I will get to leveling my main team and hopefully the starting zones won't be so ugly as day 1/2.
