Really happy to hear something is being done with quest XP.
The list of decreases is a little odd. I could name (but I wont) a good many quests that have WAY too much XP in them- none of those 4 would be on the list (or even close, honestly).
The list of increases is good. Really pleased with House C being on there. I absolutely dread doing those quests to flag, the XP is just awful.
