I've mentioned this before to staff and I'll say it here as well as a tl;dr.
This isn't a simple number change and isn't one that can be quickly done. Modifying rates of the original dungeon drop tables breaks the table for the dungeon and all mobs in it, so it'll have to be remade from the ground up. So to remake all beginning dungeons takes time, if we decide to go through them all.
As for the rates, since they were done via file and not some hidden buff, that's a bit more complicated to do as well. I was thinking of reverting to release files (prior to the rates being put on) and readding the new changes to that. Doing that would allow for easier access to all other drop tables and make it a bit easier on me with making them, though readding all new ones and modifiying them to the old drop rate is another battle. Basically have no drop/exp rates and leaving it as base, then throw the rates on a general world buff like Battle blessing. This could also allow for an "exp block" persay for the lower cap level players.
