Normal looked boring as hell, people said the same stuff you said, remember how much more "epic" it was on hc?
You don't? Well thats because it wasn't.
The normal mode mechanics are always the basic concept of a fight, the skeleton if you want.
If the basics are already bland, hc won't be super epic awesome sauce, it will be bland with some more damage and most likely more adds strapped on it.
So far Garrosh doesn't really look that appealing.
Will be lots of fun due to high aoe deeps, but thats it really.
