If I were to take a wild stab in the dark, maybe they were trying to explain that there won't be enough tokens to get the achievements done, plus purchase pets.

I have everything done on my main, but I have one alt I was working on the "Long Strange Trip" with. I personally wasn't thinking about it on the Lunar Festival; when I got 50 tokens, I went and got the lantern to put up on the AH.

I finished up every thing else, and realized that I didn't have enough tokens to buy the dress for the last achievement. I didn't whine about it tho. I just smacked my forehead, and moved on.

I'm pretty sure that I am not the only one that did that.

This does warn me, however, that they know ahead of time something will be broken.

I see downranking in my future, but here's my theory:

Blizzard knows that they've spoiled the "casuals" by basically caving in to the "but I don't have TIME to play your game - can't I have [oh so special shiney] anyway?" in most every other aspect of the game. They know that they will get a larger than usual number of tickets entered from folks who want an LFR version of "Long Strange Trip" that you can complete in a weekend, and they're trying to manage expectations in advance.

Excuse me, but I do seem to recall that the Brewfest ram was removed from the vendor and turned into a random boss drop due to the QQ of raiders who complained that a) they didn't have enough time to fit 20 minutes of dailies into their busy raiding schedule so they can earn enough tickets to buy one, and b) something so awesome doesn't deserve to be possessed by casual low-level scrubs and should be reserved for only the max-level elite who can down holiday bosses.
