I do the same all the time and maybe 9/10 times the player either dont listen or insult me rather than taking my tips and hints. If you ask for help why on earth do you yell at me like iv just kicked you in the balls or something?
Anyways i agree with you OP. LFR for me now is just a grind to get those damn titan stones, once i get those i dout ill step foot in LFR for a while. I think those that are a little lower in terms of gear often is alts and the player that plays said alts just want to gear his alt up asap without really enjoying his new lvl 90, and i cant seem to grasp why.....
