Teaching a noob the ropes and regularly grouping with them are two totally different things.
also there's nothing wrong with your last topic:
https://forums.d2jsp.org/topic.php?t=82624121&f=272Being brutal about it, people will generally rather not group with players whom don't have ~100 ee weapons from level 25-55. You're in a little bit of a vicious circle as you don't really have the FG to buy the gear either. As a tip clubs or staffs will be cheapest, however you'll be forced to use a rogue if you use staffs, although as far as i've seen staff's are slightly more available right now and there's nothing wrong with rogues.
I also prefer to solo find "treasure" as it guarentees i get it. Not seeing a reason anyone will be jumping for joy at sharing their loot when they do 90% of the damage.
So if solo play is boring to you, you're going to need to find another source of fg. Not sure how d2 is a dead end, still a tonne of trading going on there.
If you can live with solo play then you can make fg here and slowly build up your FG to get better and better (i regularly needed to solo play 1-mq as my gear was bad when i first started)
You'll notice a few players will have open groups which you'll be free to join, although these will usually be whistle climbs which in general are much less likely to find loot, arguably 40+ whistle climbs are done per week and we rarely see anything in good/sexy drops from them, whilst imo a solo explore climb will find something worth 50fg+++ every 3 climbs, i had one worth 10,000 fg not long back.
