Here’s my take:
The root causes for the stone xp nerf and how to make people happy while still nerfing it. Fix the reason people are using these “exploits”. There are more, if the causes aren’t fixed it’ll be a cat and mouse game until all crafting xp is removed.
XP gains from some activities is low and this was supplementing it. Normalise and maybe even buff everything a bit and there will be less complaints.
Teaching pie was abused, change it to quantitative rather than a timed buff. Make it not expire between logins though, I don’t see how that has abuse potential if it’s quantity based. Make it a bit higher than 20k too, 5 pies for a level is too much.
Make skillpages equal or better than alts, especially in the early game. After you pass lvl 20 you’re miles better off with an alt than a skillpage since you can get a fair number of skillpoints on an alt a lot faster than your existing character and the alt’s levels don’t make your main gain new points slower. Don’t draw skillpoints from the same pool between the pages. If they want to keep progression slower, make new skillpages have maybe 50% skillpoints of your first page always available to them
Plot gain will be slower. This is the most complicated one and there are multiple threads about it already. Space on planets is limited so there are legitimate concerns with ease of access to plots, griefing potential too but I think that’s less of an issue since you can already grief with just a single plot.
Some quick fixes that sound good:
Or separate plots from xp somehow, but that’s a bigger topic.
