Nowhere have I ever said that 25M was superior. I mean, fuck, I was a 10M Heroic raider for most of MoP. I often get accused of 25M bias since I favor WoD's larger raid size but I've also argued why it's necessary ad infinitum as well. Class representation matters in raids and it's a core tenant held by the developers. No amount of sappy, heartfelt "Blizzard killed my super tight-knit 10M Heroic guild and now I hate the world because I can't replicate that experience in the live game anymore
" bullshit stories are going to change this fact.
As for logistics: That's something you and I will never agree on but I don't think it's fair to completely discount my opinion on this subject simply because more people would prefer logistics not to be a part of the Mythic raiding equation. You and I have fundamentally different viewpoints on what makes a raid enjoyable. The difference is your viewpoint is generally more supported by players and my viewpoint is generally more supported by the developers themselves. Label me a shill if you'd like, but I don't think it'll be changing any time soon.
