The Patchwerk 10man achievement requires 24k raid dps. Nowadays 24k personal dps is quite good. Not quite soloable, but that's the scale of outdated we're talking about. Heigan's Eruption does 7k damage every couple seconds, not nearly enough to kill anyone anymore even if they tried to die. You can get Malygos down to 1 hp in phase 1. The only one that might screw people up is Shocking! because the slightest touch fails it.
Zerging Sartharion is in no way comparable to the original hard mode. It's still fun, and don't think I'm trying to discourage anyone from doing it, but don't pretend it's hard. I'm glad you enjoyed getting your Red Proto-Drake, and like collecting mounts, but try to see it from the point of view of people that busted hump every week when it was new and difficult for their prizes. You weren't there, like you said. Doing it in 2011 is not at all the same. Showing off (like you said) that you and your friends beat Naxx achievements now is beyond silly.
The developers know full well that "Glory of the Raider" drakes would be trivially easy to obtain now; it's up to them if they think giving everyone one would be a good thing. Currently, the reward for 'putting in the time' to take a port to Northrend and punch 2.5 year old bosses is a big pile of achievement points, and I personally think that's perfect.
P.S. Giant old-gear bank bag for 9000 ach point reward, make it happen!
I'm glad to hear that your raiding group is able to zerg bosses so quickly. It's quite impressive and if I recall correctly, is worth a few achievements in and of itself. The group I go with still regularly wipes on things like Sarth, KT, Maly, and Ulduar bosses. I could theorize as to why, but that's not the point. The point is we're not as good as you and that it is, in fact, still a bit tricky for the people in my skill category to beat old raid bosses.
Does that mean we suck? Probably, but we still have fun attempting these things. We still haven't beat Ulduar, actually, and that's with most of us being at 85. To us it feels like a downing the bosses and doing it in a way that earns the achievements is quite a feat and something we want to be able to show off to each other.
Is it really? Obviously not, to people like you who already have the drakes and an easy time with zerging the bosses now. Kudos! You're awesome! It IS impressive to do what you've done. That's why there are rewards for it.
But I think we're always going to disagree on the significance of those rewards. Those advocating removal see it as a trophy item, something they got when it was hardest to get and therefore anyone who doesn't face the exact same difficulty they did should never be allowed to have it. It is a trophy item, something to show off to the world and say 'I am better than you' or 'faster than you' or 'I have been playing the game longer'. Probably all three.
Me? I'm saying the exact same thing. And then I'm offering to help my guildmates reach that point too. "Look! I have a shiny bronze drake! Oh, you want one too? 'kay, lets go run Stratholme!"
