A limited-time daily quest boss with a rare mount is apparently just what Blizzard thinks the WoW Valentine's event needed.
In all seriousness, they've apparently revamped the entire event into a token based system after last year's debacle - Lyriana, my level 80 EQ2 character, was literally born during an evening I spent logging into WoW exactly once an hour to hit on the city guards. All of those achievements (even the once rare "perma-peedle" pet) are now guaranteed token drops, presuming the event is long enough to collect enough of them.
Of course, removing the RNG from most of the event doesn't necessarily change the complaint I raised about the easter holiday, in which Blizzard continues to design limited-time world events around a minimum amount of time investment they are hoping to get out of players. Did they get it right this time around? Not my problem, I've been there and done that.
Best of luck to anyone trying it this year, it can't possibly have gotten worse.
