2. You don't agree with number 2? Its a fact, you get 3 res's compared to 1, 3 people are alowed to 'oops, my bad' and you don't lose need to lose a player.
3. Any guild, most of my guild have 3+ Alts and are capable of playing them all to a high standard, so lets assume you have 30 raiders in your 25 man guild, thats ~90 toons to choose from. I know thats not 100% accurate depending on what toons people have, but DPS is a dime a dozen.
4. If 25 is harder tuned in this expac, it will be the first time it ever has been (admittedly, not played 25s this tier, but I'm inclined not to believe the 25 man guilds that say it is, because they always say it is, even when its clearly easier.... gg for misplaced ego and elitism). The 'hard' part of 25's is carrying the inevitable dead weight, not the tuning.
5. 10man - 2 pieces. 25 - 6 pieces.... does not compute, should be 5, and even then, as already stated, multiple drops of the same thing = speed gearing.
Anyway, I've said my part, its fact, not opinion, and I refuse to argue the points with people because arguing with wow players is like trying to discuss religion with the religious.
