Dude you are totally delusional. We have done everything in 8m and everything in 16m with the exception of final phase council 16m which we tried for the first time last night. I can say without a doubt that every fight is harder in 8 man. Everytime we do a 16m everyone in our chat is saying how it is faceroll. I love when these uber guild guys come in and claim 16m is harder... Having done both I just have to laugh at them.
So have we and 8 man is significantly easier in almost every fight so the only delusional people are those like you. The fact that you have better gear than we did when we did it (before nerf) and struggle with any aspect of the fight (after nerf) just shows the difference in skill. Hence, my point in that 8 man guilds that can only do 16 man content with superior gear and more experience is proven.
