This is a common thing people like OP think when their playstyle or community suddenly changes.
The best example of this is Master Loot.
Someone who only ever raided in a fair guild with friends and family thinks that the removal of Master Loot is bad.
They themselves never experienced it being used unfairly so it cannot be bad.
But in reality this is only their percieved reality, real reality is different.
OP most likely did not use to PuG much or at all before but now he does PuGs on a regular basis so he experiences in game systems differently.
The game is not being more focused on PuGs.
But certain gameplay elements or even grouped content is percieved differently by organized and by not-organized people.
It is only logical.
I personally PuG 95% percent of the time so my opinion on certain things will be entirely different than someone's who does organized content 95% of the time.
The main point here is to not try to force your view on others.
If you hate pugging, don't do it.
If you don't like being dependant on others, dont join guilds.
