Consider this...
10m
Drop 1 Emblem
2 Pieces of Gear
10% Crafting Material
25m
Drops 2 Emblems
4 Pieces of Gear
50% Crafting Material
The only difference is the pace at which progression occurs, 25m will still gear out faster (not better) and it will allow more versatility for guilds and low pop servers that can't do 25m raids. In a game environment where gear becomes obsolete within 4-6 months of it's conception, the only real motivation to gear is "how fast can I get it before everyone else does." That mentality it exactly what these new 25m cater too and why people will still run them.
