Dear OP, I don't know how to say this in the nicest way possible.... FF14 is EASY EASY EASY game with maybe only 10% of the content is reserved for "hardcore" gamer. There are countless videos (3 minutes long for each guide) to show you the bosses mechanic - and a short description on Wiki FF14 on what you should be doing. ALL of the level 15-50 dungeons teaches you the basic mechanic, you also have guildhest. The high levels 50 dungeons are also fairly straightforward and many players can give you quick tips on what to do on each bosses. Level 51-59 dungeons are rather easy to figure out as well. Bottom line, as harsh as this sound, just get better and use party finder to practice. Otherwise you can just do crafting, or if this is too hard, maybe this game is not for you.
