I'm happy I didn't get my hopes too high, neither of these solutions are going to help. Ultimately, you're just going to cause disgruntled players fighting over spawn points. You just need to make Unity/Escha/Reisenjima Monsters that drops the items that are needed. Let us use the stupid Crystal Petrifacts if you make it a Escha-Reisenjima thing as a spawn trigger, that way people will still do VW and maybe get a few items here and there.
Next up, If you also want to help the players, Give them Special Trusts, A WAR(August Clone), BRD, BLM/SCH, and a WHM that are specially designed for Abyssea and Voidwatch that will Actively SEEK the weakness triggers for Mobs. I know this is asking a lot, but if your not going to bring a wall down that not needed, then you need to give the tools to make so we can still climb it.
Personally, I'd prefer the Escha route because it can be more useful for end-game and helps for things that are being built for the end-results as well.
