So you hurt your DPS against 98% of the enemies you'll fight in order to avoid seeing an immune message on the other 2%? We are talking about more than just pit fiend DPS here. We are talking about DPS against devils, demons, gnolls, giants, trogs, kobolds, undead, trolls, ogres, beholders, mind flayers, hobgoblins, orcs, bugbears, minotaurs, etc.(Just name every evil creature in the game) You, only other hand, are concerned about DPS versus elementals, mephits, vermin, animals, and the few other neutral or good creatures in the game. I actually have played nearly every quest in the game over the past 3.5+, which is how I know that Holy works on nearly every type of creature in the game. No matter what the level, I always prefer to have Holy weapons over Pure Good. Of course, I keep some Pure Good or Greater X Bane weapons handy for the occasional neutral mobs. I don't plan on trying to use the same weapon against every single creature in the game.
