Herbs is a good temporary solution, I hope this is just temporary and you plan to do something real in the future. I can understand that some changes require a lot of work and this is temporary. But let me just say what about base xp, why don't you increase it at least in lower areas 105-110 so people can catch up.
What about the rune stones, everyone needs them but the only ways to get those are Dim raids once every 2 weeks for 1h, what if you can never be there at that time cus of life. You can try to do Balok a boss 97 that once you reach 103 no longer drop Rune stone, yean with 2 groups inside low chance to get a rune stone x14 people, how long will it takes to get 8 rune for just one skill? I'd say at least a year just for one skill. What about making them available in clan lv8 or more not tradable to replace the supply box that you removed and never replaced by anything to make it accessible to players.
Just an exemple here, I made a Tyrr Dread who is 105, I need just on him 28 rune stones for 4 skills, I can't even get those skills which makes the character much weaker than it is supposed to be. You removed all ways to get any adena drop, so can't afford them also to buy from other players who sell the rune stones around 90m-100m or more, just do the math here 28 stones x 90m that's 2.52b adena if you try to buy them, some of those skills are for skills lv98 or lv99. Do you really think someone lv99 can afford Rune stones? I am not talking about gear, exalted is ok stuff at that level still, I am talking about some skills that could make the toon a little stronger who can't even use his skills cus there is no ways to get the damn rune stones at this level. IoS adena can't help a toon like this, plunderous can't help a toon like this even if they had the adena they once had, you can't even xp there anyway. you have a good way with the coal mines to shave a lot of time grinding to 105. Why is there no ways once you get 106+ to get some decent xp anywhere? Why is there no way to get the Rune stones anywhere. We all paid the price when you removed the Dim rift which was very nice for rune stones in the past. You removed it because people were abusing this system, what about restoring it but make those rune stone or codex not tradable? this way you prevent the abuse of Rune stone and make it possible for those in need to get some at least.
In the end all I want to say is please think about players who are stuck at home, with reduce incomes that can't afford spending every month in a game they already spent a lot of money after all those years, even before the "truly free". I remember giving you 15$ a month for years to play this game. I also remember that when I could put some money here and there I was glad to try my luck with some events. I remember having prestige packs for years but cancelled my subscription cus you hardly listen to players and think L2store mostly to make profits. Keep in mind that without us all those years, you would be without a job now if we didn't keep playing the game. there is plenty of games out there that only require to buy it and then you're done and you can enjoy the whole game without spending one more dime to it. Feel lucky that players are willing to still spend some cash so you can still have a job. Feel lucky that we all love this game so much, we are giving you the opportunity to recover from all this mess updates after updates, nerfs after nerfs, removal of ways to get some decent xp or adena. It is not with some random xp events that we can grow, something has to be done either the base xp from mobs or the xp table for level has to be reconsidered.
