I agree with Thebitterfig.

I am a 10 man raider for one reason: internet issues, anything more than 15 ppl and i couldnt even move, let alone pull my weight, so when i recently got my internet upgraded and walked into a 25 man raid(ulduar), and saw the number of ppl just clustered on each other for XT.....I was SHOCKED, it seemed like one mistake and half or more of the raid would be wiped out by a light bomb if someone wasnt paying attention, wich did happen btw, a rogue killed half the melee that way when XT was at 25%, and no one so much as even batted an eye, the rogue was even making "oops" jokes over vent, easy content yes, but killing 7 ppl because you were an idiot IS NOT funny.

The point I am trying to make is: Being used to 10 man raids, 25 man raids are both crowded, and not really epic at all, taking down the all powerful XT002 Deconstructor of Ulduar with 10 highly skilled ppl seems MUCH more epic than taking him down with 25 ppl and basically overwhelming him with numbers.

Just my honest opinion.
