Actually with the roulette they also benefits from getting highly geared experienced people, which wasn't the case before. It's a win-win situation for all but the complainers.
In response to that I say this, because of the fact that we can't queue together in the roulette we don't queue at all individually. Why bother if we can enjoy the game together? This means that the roulette now loses 2 potential people. And as I mentioned we do queue for lower level missions to level alts but we do specific ones so that it isn't a waste in regards to gear drops. If we could queue together we would go into the area that needed us.

Personally I'm fine without the roulette. I can get everything out of the game I want without it. But if the option was there for parties of <4 to queue, it would be utilized more by my friends regardless of incentive. And that is a fact you cannot deny.
