I presume you are referring to public games, channels, etc.
HC is actually really bare in non season when season is going on, especially in the higher torments. So wait and play the season.
As a side note, SC is similar except since there are a lot more people there, you can still play non season SC with a lot of players in the pool.
Hope this helps and feel free to msg me with any more questions as I am a long time HC player. GL in seasons
