You join a stupid guild.
you do your solo dungeons, those get you jewelry.
You get good crystals, people will less likely kick u if jewelry and crystals.
u join RG runs, people usually dont kick u for being shit there, get gold and jewelry.

Which dungeons are you trying to do? Brnm and rgshould be very easy to beat. you can also look in lfg section

What server are you playing ?
