There are 3 or 4 Dungeons that are free. Try them first, see if you like the vibe. They all have some kind of jumping puzzle lol. They dont have match-making, but they are in the FTF. You can also add me, always down to teach a dungeon. There's a quick trick to see which ones you personally have access to. Open the FireTeam Finder, click the blue "search" side & select "Dungeons"... it will show a list of all the Dungeons in the game (newest to oldest) & it will grey out any that you dont have keys for. The ones you do have access to can be launched solo from their respective planets. Shattered Throne from Dreaming City, Prophecy from Eternity, etc ... If you wanna spend money on Dungeons keys, just remember that there were 2 Dungeons per campaign for a while. So, SunderDoctrine & Vespers Host are both on the Final Shape key... Warlord Ruin & Ghost of Deep both on LightFall key ... Duality & all the dungeons that came after, have their own exotic weapon that drops from complete RNG at the final boss. Grasp of Avarice has its own quest which rewards the Gjallarhorn. Shattered Throne has a quest for the WishEnder bow. A lot of info, but I hope it helps.
