the frigid frostling! or at least that's what it sounds like from other players so far. i haven't had any luck on my alts, so i can't really say for sure.
i haven't heard of any news about the searing scorchling returning to the midsummer fire festival boss loot list, so there's still a possibility that we'll see our fiery friend as a drop from the new 4.2 daily hub goodie bag.
as far as the midsummer fire festival goes, it doesn't seem as if anything's changed from last year. one attempt for the pet per day, per character. the holiday loot bag is still soulbound. the capes that drop off of ahune as well as the frostscythe have had their ilvl increased to epic 353. and the fire festival vendors still sell the same items for the same blossom prices.
i'd be lying if i said i wasn't relieved to find that things weren't changed around again. good luck to everyone going after the frigid frostling this year!
