You're right but since 90% of players want to become gods without effort all will run them via GF and finding group won't propably be easy
Be 'as' easy as before. But, it's very likely that most people at 180 rating are going to continue to do their own pug runs outside of GF for the same reasons you've listed as well as earlier reasons.
The only thing this is doing is giving the undergeared somewhere to go to get geared. Those who don't need it won't have much reason to run GF for their SMs so it won't effect them at all.
