Ok, you've cleverly shown us how you can flip the xp of a single quest on a dime to whatever you want, without it affecting complex, across the board xp formulas throughout the database.
Please use your newfound powers to do what players have been begging for for years. Please increase Amrath XP.
You know that a sore point in the game is the exponentially increasing XP requirement for TRs, and you know that there is insufficient XP from 18 to 20 for TR2+. You know that the XP for Amrath is too low for the effort and risk required, resulting in one of the (otherwise) best designed areas of the game collecting cobwebs and pixel dust. So please just kill two birds with one stone and fix it already.
Or, if it conflicts with some long term plan whereby new 18-20 quests are coming or all the formulas for late heroic xp have changes in the works or whatever, please give us a clue as to what that plan is.
I think we've waited long enough on this issue. At very least, if you are never going to fix it, just say so, so we can stop hoping.
