Your opinion is not universal. Some actually enjoy current raiding, and will think the Arthas death is epic even in normal mode.
The nice thing about the way they're doing it right now is that people doing it in normal, or 'easy' mode, doesn't stop you from doing it in hard mode. Really it seems the only valid complaint is that either the tuning on hard mode is too hard, or maybe there's no 'medium mode' (not to give blizzard ideas). "BAWW other people can do this on an easier difficulty setting!" is just bawwing.
