You are clueless if you think people can qualify withn 30 minutes on timeless island. It would take about 8 hours at minimum, and that would require some good RNG as well as not being ´clueless´ about how to do it.
People who are clueless on Timeless Island.. they are about ilvl 480ish. Sure, you get many armor slots, and even maybe 1 or 2 535s.. but you also have no 2nd trinket and no weapon. Want to buy a TI weapon ( which also will not get you into SoO).. trust me, it is NOT fun trying to farm 20,000 coins on a character that is at iLVL 480ish with a crap weapon. In fact, I would say if they earned 20,000 coins on a character with that type of gear.. they are far from clueless.
LFR is always going to have people not giving effort.. who cares.. bosses are dying fast already in everything but the latest wing, which is basically same as it´s always been with LFR.
