have you even done both 10 and 25 man, i have done both every week since the start and by far 10 man is faceroll compared to 25 man, my alt is just doing 10 mans and its pretty much as geared as my main doing 25 mans so before posting get your facts right.
Its a fact 10 man is easier compared to 25 man apart from 1 encounter that is slightly harder on 10m, dont post when you have no clue on what your talking about.
The reason there are more 25 man kills is because more ppl prefer to raid in 25 mans and the top guilds are all 25 man.
