If you have 25 good players, then 25man is easier than 10man, but finding 25 (actually like 30-33 GOOD players because of the possibilty of ppl signing off) is 1k9iiojfsajkfnsljknglsjnklgjn harder than finding a good 10man grp. I have been raiding hardcore and semi-hardcore in 5 different guilds since late TBC, and I've never been in a "perfect" raid, where nobody fails, always 1-2 or more dragging you down at different points. Guess that's a luxury that only the top top top guilds have...
