I want to up vote this... we used to see a year+ schedule. Those have gone without update to the guides.
3 days of great pet battles during pet week. Sir Galveston on Friday and Bhodi on Saturday in Dalaran, me with 1400 pet bandages and a toon to level (you get toon xp from those 2 fights), then Squirt on Sunday. All total I maxed out at least 300 pets, putting all my pets to 25. Of course I've already picked up more pets to level, finding out that I never bothered to collect Deepholm pets. No big rush though, I can level them easily through Draenor pet masters.
Of course I learn of important information a day after it ends. As usual for WoW material. I think that is why I kind of quit.
