OK, that was a weird post, especially the end…
Where did you get the idea that SSF is for streamers / full-timers?
The key of SSF is to enjoy the game at leisure pace and don’t worry about getting the very best gear and min maxing everything. The complete opposite of what most streamers or other non-casuals do (they try to rush to the end, get all the possible OP stuff, and use any trick they can find to make easy money by trading).
That said, for that very reason, your main point is correct: the biggest part of the population, and more importantly the one bringing the biggest amount of cash, is found in SC.
Precisely because they want everything easily and quick. They are the bread and butter of all Pay-to-Win systems (doesn’t apply to PoE or LE, I know).
drop rates go brrrrrrrrrrrrt. Trade is not the best solution to items that you drop having some value you can realize and items you want but have not been able to aquire through appropriate amounts of play. Some posters continue to harp on it though for “reasons”
