[Lordaeron] Bring back actual challenging content

The average gear on top of the nerfs upon nerfs to the content has made Lordaeron a walk in the park compared to what it once was. Bring back higher boss HP, shorter enrage timers and more parryhaste. We have Icecrown for easy content, Frostmourne for a more blizzlike progression system (ignoring the item shop) so I suggest we bring back the old Lordaeron difficulty back, making it a realm for truly hardcore challenging content.

That's all fine and dandy but consider this - if they revert the difficulty back to very hard, once mid-tier and low-tier guilds can't progress they'll leave the realm and Lordaeron will die. Current difficulty is balance between hard and doable.
