So you cut 10 players (roughly) and took the better 20 and got more progress... Now just to invite another 10 players to my 10 man guild and cherrypick the best...
I take it you consider your opinions to be smarter than most peoples then...Now try keeping a 25 guild together under those circumstances. Blizzard killed 25 man raiding. With basic economics. Fixing it will blow everything up, so IMO take that knowledge to Titan, or maybe actually read forums when smart people are talking!
