What is deeply flawed is your simplistic and naive view of what it is to run and form guilds and raid groups (which is not surprising given your lack of experience in it). But as I stated before, in reality you don't get to just pick your 10 best players. I gave reasons for this too: not every one of them will want to raid 10 mans, some will transfer, some will quit, some won't have the classes you need (when we did this, if we'd picked 10 of our best players we would've had 3 locks and 4 priests and 3 rogues in our 10 man). In reality there's no reason to think your average skill level will raise in any significant way, certainly not significantly enough to explain the massive progress jumps you see when guilds do this.
Also note that nowhere did I say guilds break into 2 groups, again this is a result of your simplistic view of group dynamics.
You keep repeating this over and over. It has been debunked. Deal with it. People go for the best effort/reward. Now that's 10s due to the lower skill requirement and faster progress. Your argument simply holds no water when you look at what happened in WotLK. If people actually really preferred the convenience, ease of joining, etc. etc. 25 mans would've died in WotLK, but they didn't. Few more ilvl is not going to "force" anyone to do 25s if they really prefer 10s.
No, that's a strawman you've constructed. 25s don't break into equally skilled groups. They break down into one 10 man with whatever combination of players are willing to join and provide a workable class combination -- it's incredibly unlikely that the remaining 10 will all be above average from the 25 roster (for the reasons I've given multiple times).
