Fractal Levels: The Trinity LFG is back!
Most people either run with the same group, make a guild specifically for Fractals (https://forum-en.gw2archive.eu/forum/game/dungeons/FotM-guild-created-Ranks-editable/first#post809512) or, most commonly, use a third party LFG tool since Anet don’t have one capable of the job (http://gw2lfg.com).
Between those methods you can usually find a group at your level at most times of the day. But yeah, it’s not ideal.
