When you dont have time, efford, dedication, skill what so ever to do end game raiding => dont do end game raiding => dont get frustrated by lack of your own skill or efford to actually learn job or fight.
The thing is that some people clear A6S AFTER they get full 240 and it should be enough alarming for them to know that they WONT ever finish raiding tier like this.
Improve yourself or stop crying on forums how hard it is cuz it is not THAT hard, people are just lazy f***s.
Long story short....learn your role -> go raid.... Seems like for some people would be ideal to raid once per week 1 hour session and like in 1 month clear A12
+ I dont really get why non-raiders are actually commenting on content that they never did. Are you usually like giving advices to people that are doing completly different jobs or something ? Just go for some rullets or Weeping City should be challenging (oh wait, no...already over geared for that so its boring, right ?)
