Nowadays participation mostly depends on gear, not abilities. Parties will seek players with for example "at least 5K GS", which means 5000 GearScore points according to a popular GearScore AddOn which analyzes your equipment. The Dungeon Finder (with which you can find random parties for random instances) also employs a gear filter, albeit less outrageous than human players.
