If they arent paying attention to and anticipating limit break, odds are they also arent coming anywhere close to maximizing their dps potential anyways. /shrug it is what it is and no its not a new thing. Everyone starts somewhere, learns at their own pace and blah blah lol. You can be a jerk about it, or try to teach every person you come across. Or do what most people do and accept that queuing with randoms is a mixed bag and just silently take it in stride. Or if it bothers you that much find some like minded people and stop queuing with randoms. They added the ability to do roulettes as a group some time ago.
