Judging from the comments on the last post, I think some people may have misconstrued my sentiments about heroic difficulty. Here's my real thoughts:
Heroics need to be nerfed.
Just so you understand, I've pugged every single heroic. I had full i346 before I got a single piece of raid loot.
Heroics are hard and challenging. But they need to be nerfed.
Why? Because of the space heroics currently occupy in the game. Heroics are a necessary stepping stone to raids. If people fall off the path in heroics, before they ever get to raiding, raiding will be a disaster this expansion. What's the point of 4.1 with new raid tiers if the majority of the playerbase is struggling with heroics?
The decision to release raids with Cataclysm was a total mistake. If raids had not released, heroics would not be a stepping stone, they would be the current endgame. And they are pitch-perfect difficulty to be endgame for a couple months.
But with the route Blizzard took, heroics are not endgame, they're a mere stepping stone to endgame. And they are too difficult for a stepping stone, given the probable timespan to the next major patch. Thus they need to be nerfed to match the proper difficulty for their placement.
