They shouldn’t be pleased. They asked for “x” and then blizzard gave them “y”. Blizzard also said “you’re welcome” go horde for “z” if you want “x”. Blizzard is now giving them “y/x” and is patting themselves on the back. This isn’t hard.
Yes a few of the high elf crowd are doing it the wrong way. But holy moly. Just imagine, seriously imagine, if the horde got void orcs instead of Mag’har Orcs. The people previously asking for Mag’har Orcs would still be asking for Mag’har orcs.
