Why do casual players seem entitled to cosmetic items added in game?

2) the reward is no more “casual” than it is “hardcore”. You specifically use the analogy “what if BIS was locked behind IS” directly implying that this is a casual reward locked behind high end as your analogy is the reverse. What makes this a “casual” reward?

Here's a key difference. A non-raider has no use for BiS gear. All players can use a hairstyle.

Does that matter? I'm not even sure. This whole episode and the nasty reactions have soured me on the game tbh.
