Why people are getting mad about warlock restriction being lifted?

[Dedaru-moon-guard (Dedaru)]

You guys do know Blizzard planned on doing this, right?

You guys DO know that Blizzard has said on multiple interviews that they wished to open up all classes to all races, right? Hazelnutty interviewed Ion himself and he said this. Why is it all of a sudden people are SHOCKED and APALLED when a good number of us roleplayers will probably land on our feet when it comes to these new Warlocks in coming up with some new backstories and such.
