They also do it when it is of convenience for "balance" if you include the sneak Bloodsail Raider nerf and Water Elemental buff (Balance is in quotes because Bloodsail Raider wombo combo is weaker than Patron Warrior is right now).
Jeeves, Divine Favor, Leeroy+Knife Juggler, Holy Wrath+Molten, Sapping to a full hand (I mean, you gotta at least have like an official rules document saying "sapping to hand means destroy a minion", it's not like the operation is inherently defined) and now Mistcaller all have this "our code is right, our wording is right, your english or basic logic must be wrong" garbage to justify bad workmanship. There's so much of the garbage that I forget some of it, like Shadow Madness, which is just not worth it for people complain about when there are other things wrong I guess.
Someone reported in the forums that Core Rager can't be played as a 7/7 while Starving Buzzard is out, which directly contradicts Warsong Commander's behavior with Bloodsail Raider. Either "When you summon" triggers happen first or battlecry triggers happen first, not both. They didn't even make a consistent switch.
