The short and sweet of it, reroute the assist system to POH. getting POH to where veteran players can help assist newer or casual accounts. as well, get to show off all the cool things they've gotten over the years. which creates a moral boost for both players.
in the old days houses were used for prayer training, teleportation hubs, letting other players access some useful stations, etc. now, there are so many other in game systems that do the same things, but are way more accessible. POH shouldn't be in competition with them, especially when there are other ways to embrace this old role.
plugging in a way for high level players to share levels would be a huge boon. it would help tie veteran players in with newer or casual players. as well, bridge that ever growing gap of content that casuals can't ever seem to get to. one of the biggest interest killers for casuals is getting to the top levels to use things like elders, or other craftables. it also gives veterans a more personal way to help people - as is, the best way is to just give out cash stacks. this can even help future proof raising levels without alienating players.
my thoughts would be to create special rooms for each skill. with stations that would give access to the hosts level in that skill. as well, removing the limitations that keep the host from playing. instead, the player using the stations would inherit a fumble % and an item count cap. along with other abuse protections.
with the road map, y'all shared your idea to help players show off their adventures. adding an assist system to POH gives good opportunity to expose casuals or new players to all levels of content the game offers. going in and seeing trophies or quest rewards that link to content some may not have ever known about.
