This is some good info, particularly since I'm running the gauntlet of crafting tailored weapons for each...
It occurs to me that we need a calculator, to help us know when DI is necessary and when it's overkill, or when you really never need to bother with EoO. In other words, some sort of spreadsheet that calculates your weapon damage multipliers and tells you, "Enough is enough, mate. You've hit the damage increase cap."
