The damage reduction multiplier is higher than the damage boosting multiplier. Retro AP would not be effective on constructs, as the piercing resistance reduces more damage than the elemental weakness boosted.

I wish we could have kept those split-abNormal types, because I rather like how they act as "anti-types," with which OOO could do fun themed things like, say, a Shadow damage weapon that inflicts Freeze and a "Radiant" damage weapon that inflicts Fire, as well as more practical things like offering weapons whose damage types dovetail with other single weapons.

I too am failing to see plausible reason to remove the anti-types from the game; I can understand changing to a more familiar type out of fear of making an adjustment and getting it wrong, but since the change came with the epic Shard Bomb overhaul I can't see such fear as a plausible explanation. I'm very nearly sure I recall correctly that LD was introduced before the big change, so does any one here have much memory of how the old RSS and Jelly guns fared there? Were they way outta line, (or, rather, outta point cloud with just barely enough bias to force a linear regression if you push hard enough?) compared to whichever weapons people currently complain about seeing every clone and its grandma using?

The numbers provided for unboosted damage are a bit different from what I've been imagining they'd look like. I expected that, when adjusted for overall greater monster family resistances, anti-types would behave most similarly to half-Normal types, except that I would have predicted that intermediate values would fall noticeably lower in that range. Instead, to me the actual numbers look like those for half-Normal, without that difference.

Do your data show that the disparity in benefit from damage boosts for big-hit, half-Normal weapons like most swords relative to closest single-type counterparts is much milder than the disparity in proportionate boost between hitspammers (like Cutter, Jelly guns & Autoguns) and heavy-hitters? I did not consciously notice a difference for half-Normal vs. single-bar types when I was bringing swords to almost every level, but I was struck by how dramatically my Autoguns gain compared to my other weapons.
