What's with the Early Pull Brigade?

I liken it to content in a video game, personally.

The point is it has entirely to do with an individual's attitude and temperament as well as their overall socialization. If a person is impatient and self-centered they are more likely to believe any social system that does not directly or solely satisfy their needs is stacked against them or useless - and despite it's beneficial nature will either try to subvert or discredit it in some way.

I generally point my more individualistic and impulsive friends towards shooters as even their online play is catered towards individual wants and rewards - there are still teams obviously but, unlike an MMO, there is less/no emphasis on cooperation and teamwork.

Hunts are the first situation in which this community has had the opportunity to derive order from chaos and emphasize cooperation. I choose to encourage those things - rather than throw them down.
Popping an S rank all alone - or even in a lone party is very time consuming and rare. People working together and being courteous to each other isn't a bad thing. When individuals consistently or demonstratively ignore those aspects - they engender negativity around them.
