Im all for explaining dungeon mechanics and job mechanics if I see people struggling but what happens most of the time (sadly) is I'm either flat out ignored or insulted/sworn at. It really rubs me the wrong way, I try as best as I can to not be condescending or commanding by adding '' or '^^' at the end or asking if they wanted to tips at their job. If I notice they don't speak english Ill sit there for ages finding basic skills and combos using the auto translate with emotes at the end (to try and show that I'm not just commanding them to use it) but alas, usually ignored.
