For things to continue as I want them to all I need is to maintain the status quo. I can keep helping people suck less and encouraging others to do the same. Meanwhile you've come in here, whined a bunch and just cemented the opinions of the people you disagree with.
What status quo? People ignore it all the time when Healers don't DPS in roulettes, or Bards don't use songs, tanks pull small, etc. I see people being "lazy" all the time, and the most common response is silence unless something goes wrong.

People who start poking their nose in when it's not needed are definitely the minority, but they're an obnoxious minority that usually just end up starting fights.
