@kanye-qwest There's an argument to be made for it. Ultimately, whatever changes you make to the system right now are only going to apply to how the system works /right now/, and how the system works with characters who have been built and benefited from years of working under different versions of the system. All of that seriously skews "how the system works" even in the moment, because everyone isn't really playing by the same rules. But more, every time you add a new system, /everything/ is going to be thrown off to some extent within the playerbase, and people are going to throw characterization to the wind as they scramble to adjust their mechanical abilities to take advantage of the new shiny. That's just gonna be a thing, and the only way to stop that from being a thing would be regular XP/asset resets with each rollout, so that you could actually test how the system works.
My biggest fear with this rolling implementation is that changes keep being made based on edge cases largely created by people having gobs and gobs of XP to build a character /perfectly/ designed to take advantage of the system, which often ends up hurting everyone who isn't that character. Which you have been taking into account by boosting some low-level work of various systems! But then, that leaves people in the middle, who the helpfiles say have "professional" level skills somewhat in a lull space.
But, talking about one specific thing: making hosting events more rewarding. I think the only real way to do that is to make hosting events more impactful. Adding prestige (even more prestige) to orgs and people who host events might help, but prestige should not, I think, be an ur-stat in the way it's sort of becoming (which is, to my mind, the issue with it, not just that there are numbers and they go up).
What I might suggest are a couple of different things: Fame gained for an event is a fraction of the fame of the people who attend that event, maybe averaged out, calculated at a random point during the event?. This lets social-climbing PCs know who they need to flatter, schmooze, and invite to get big boosts, AND it gives Famous PCs a chance to use that fifteen minutes of Fame to be courted and maybe win concessions or bonuses for being willing to show up. It's also very immersive and thematic -- IC Fame means that people want to be seen with you, and certain events will have greater cachet because they're attended by luminaries. It also allows people who don't want to have HUGE events throw high end, invitational events and still see benefits for doing so.
Second, throwing an event on behalf of an organization creates an automatic rise (maybe based on largesse and your Propaganda) in your reputation with that organization. Probably Affection rather than Respect, but maybe significant Affection and lower amount of Respect, because you ARE showing your support in a public fashion and taking on expense to do so, in favor of that org. Now - right this second, this doesn't mean much, because Respect and Affection don't do anything, but I assume you guys have systems in the works that will make those stats meaningful! This will position social mavens to be able to have a way to offset losses through actions, or promote themselves to orgs.
Third, allow social events to contribute towards influencing the social atmosphere of the world in a reliable, repeatable way. If a social character wants to, for example, make the defense of thralldom her passion, then she shouldn't have to just persuade PCs, but should be able to throw events that create a sway in the NPC population towards accepting thralldom as an ancient tradition which civilizes shavs and gives criminals a chance to make restitution for their crimes. And while someone could do that right now, by using the @action command, they'd have no idea how effective they would be, how many additional resources might be made, or where the NPC population is regarding thralldom and thus, how much pushing it's likely to need. If you could throw an event, put in your largesse, choose a Social Issue Of The Time (maybe predefined, maybe keyworded) and have it roll something for you and say, "This event will create a SMALL/MODERATE/SIGNIFICANT/LARGE support for thralldom in the NPC members of (Insert Ward Here)." then that's attractive, because you KNOW your character will have something of an effect. It also gives people a way to support causes they're passionate about OTHER than gathering silver and resources.
