Yeah and you need the 3x dps because they have 3x the hp. You need 2 freaking interrupts. If you have even 1 melee you have that because you need a tank over there anyway. There is no way the number of things that need dispelled are the same in 10m, you get more crap cast in 25m. You can also pretty much have every buff/debuff in 10m if you have a good comp so that isn't an excuse.
And your comparison is off. If you are 3 healing, thats the equiv of 7 healing for 25m so 16 dps versus 15 dps and the mobs have triple the hp. Its perfectly balanced in terms of the dps part so stop whining about that.
The only thing maybe easier about it in 25m is that 25m guilds can probably stack MW monks easier. There is nothing from stopping a 10 from running 2 MW monks though. And I doubt most 25m guilds actually cared enough to stack them.
Edit:
So you 10m guys will stop spouting a bunch of BS about how its the same dispels but 25m have more dispellers:

Just from 2 random logs I picked form the rankings list with roughly the same fight duration. 10m had 31 diseases and 25m had 75. Plus every poison dot that you don't have a monk cd for is ticking on 2.5x as many people.
