I can tell from that comment you have never done progression 25 man raiding. Not one heroic 25 man so far has been killable after losing a single person and having that one person stand in the wrong place, or fail to do something or DC's will result in a wipe just as easily as it does on heroic 10 man.

It is one of the frustrations that go along with progression 25 man - the fact that you have the same requirements but even more stress involved because rather than the chance that 1 in 10 will have a problem and you wipe you have 1 in 25 that will have a problem and you wipe.

Hagara alone when learning it required that if a single dps was dead without a rez for longer than 5-10 seconds it was a wipe and we started again. First kill was 2 seconds off enrage. There are some fights where in terms of difficulty alone you can argue 10 is harder - just as you can on some fights on 25 man - but the whole notion of 10 mans being harder due to your reons you just gave are both one sided and naive. It also was never a "Stigma" that 25 mans were harder and why they were awarded more - they literally were harder. This suggests you never raided in WotLK as you should know this.

I find myself at the end of this paragraph and noting that you now seem to be a new player, who didn't raid before Cataclysm, never raided progression 25 mans yet seem to have a very strong opinion about which you believe is the harder format. Bias much?
