Excuse me, but Naxx10 and Naxx25 are arguably the easiest raid encounters since the last 4 years. With of course, the exception of VoA and OS. Players like you don't get the grand picture. If your guild fails at any of these encounters as a "normal" guild, your guild either lacks the skill or intellect(Naxx10) or even the gear(From Naxx10, to do Naxx25) to finish these encounters and is indeed not qualified to enter anything that even remotely simulates BWL difficulty. While BWL was alot of stress and going beyond BWL even more, it was also alot more rewarding to alot of players.

Personally I don't desperately want to go back to those days, but that doesn't mean, that the current dungeons aren't way too easy. by way I do mean wáy.

I think it's a good thing that they're slightly upping the difficulty again, to you know, seperate the actual skilled player from the average Joe. However hard that might be to take for the average Joe, gaming is about prestige and Blizzard itself admitted that they wanted to level the playing field with Naxx10 and 25, to increase difficulty in Ulduar.
