On the NA servers I have created a new community called Carries 4 Fun; much Like Leeches and Saddles. However, this community will have an emphasis on on returning players and newer players.
Post Season 8 I personally only play seasons for the cosmetics now as I have all the stash tabs. there for i return to non seasonal earlier now. I play both HC and SC. It depends on what the Horadric Gift will be for each season. Example season 9 I played HC crusader and season 11 I'll play HC Demon Hunter (Unhollowed Essence will be free). I digress.
While back in non season SC, I typically fish open pub lobbies below T8. Why? because those are the lobbies where you typically find the new players and returners. I reform the group in T10 or T13 how often they die, farm keys for them and do Speed GRs. Tell them a little bit about gear selection, find kanai's cube for them, and tell them other "trade secrets."
Ideally its better to have more Leechers than Carriers.
I typically available for service M-F: 4AM - 6AM PST and 7PM - 10PM PST. join the community if you want to leech off me and learn a thing or two.
