I think that splitting the Order of the white lotus or raising it's cost would only make it more powerful. I basicaly agree with Garbageonly in this matter.
Order of the white lotus might seem overpowered, but in most cases you can't avoid causing some positive effect to your opponent, while suffering some negative effect. Like Garbageonly said "It's very hard to have all your tower, wall, stock, facilities less than your opponent"
When you are low on resources it is probable that you spent it somehow. Either you raised your tower or wall, or you caused some negative effect to your opponent, like reducing his tower or wall, or resources. So in this situation Order of the white lotus shouldn't be too powerful.
