the moar dps mentality came from alexander savage though.
healers were not forced to dps till that was released.
dps didn't spam their buffs at pull till then.
Raid mentalities always bleed into the average content. Look at over watch people who follow the e-sport scene or the 1%, force that meta on to the average players And it ripples.
to play properly is to work with the team. No more or less.

People forgot that in 3.0. They wanna do w.e they wanna do and don't care who they step on. Pretty much it is the meta mentality that spreads.
Note i said raid meta/scene... not players
think you need to cool your jets a little and read the whole post, instead of 1 line.
