2. Says you. Most raids I've run (and I've run most raids) ARE fun one way or another. It's mostly a matter of taste though. I also don't recall raids with "sudden death" you seem to emphasize. Otherwise, raids are intended to be challenging content that requires preparation, trial and error to succeed. Steamrolling everything would be even more boring.
3. Different priorities for different people. Yeah, loot is a big part of it, and a reason for most people to do it - like most MMOs. Many also do it just for the fun of it as well, or to help others get the loot. It's also not the only place to get good loot, especially since MoTU, so you're not required to raid if you don't want to.
4. I think this was, in a sense, updated with the idea of "commendations". Special accomplishment - a decent idea, though "more favor" is hardly the answer. Perhaps minor additional faction rewards for beating the raids on specific difficulty. Or better yet - expanding the campaign system, and including older raids in it.
Therefore, I find your post/rant very subjective and suggestions misplaced. What I would suggest:
1. Expand the campaign system. This will give additional rewards/incentive for raiding;
2. Once we hit the new stable cap of 30, update ALL the raids to be run at cap, with appropriate changes to the loot/rewards. This will return raids to the status of end-game activity they were meant to be.
