My Expanded Sentries mod has support for this mod. I forgot to note it in the change log. However, I haven't yet touched the actual % scaling of specific weapons, just put them all into different tiers. That will have to come later, the hard tweaking. I find that stuff very difficult. It's highly possible my turrets may scale too high, effectively leading to lower tiered weapons upscaling to far greater damage than higher tier weapons.
Consider yourselves on the list.I also added support to companion only weapons on TerraGuardians mod. Like the person above, I also didn't changed the percentage of damage, I only set the tiers.
I forgot to mention in the latest patch I've also added two debug items only accessible through cheats. They're used to lower and increase the scaling multiplier of specific weapons to find the right values directly in-game. I do intend the default value to hopefully be "good enough" for most cases but since I found myself having to lower the scaling of some vanilla weapons down the drain I figured I might've as well added an easy way to test numbers on the fly to speed up the process.
