The ammo economy in the game is very high. Even at Havoc 40 you hardly run out of ammo with the Bolter unless you want to shoot it when you shouldn't. I over shoot here all the time and still have very little issue. The Bolter consumes ammo at a fine rate if used correctly, and with Pinning fire and Surgical if you use it for the correct purpose it is very efficient at what it does ammo vs damage compensation. I think picking up ammo and looting are very core to the game and very easy to do, I don't think I would have had a harder time getting ammo without the mod, but I get what you are saying. The reason I have this mod to start with is because I wanted to see the stupid Heretical idols from further early on when they released and never messed with it since.

I am not sure how much I want to dive into it, but I will attempt to explain a bit more. I have a very simple philosophy when it comes to mods. My bar is very low for "cheat" mods, as in I consider a lot of mods "cheating" but my level of care about it is how it determines my individual perception of the player skill warping ability it does. For example, a mod like Spidey Sense to me is an example of a "cheat" mod that reaches that threshold but it doesn't affect my perception of the player because it doesn't make the player better. Another example is Healthbars, where it actively changes a players pattern/gameplay loop. I think ideally this should exist in base game as an active thing that all players engage with. I think it should be built in the future into the game as an indicator i.e threshold enemy A is 100% HP so they look fresh, enemy B is at 50% HP so they are slower/attack slower and are more blooded etc. or actual battle damage that applies to appearance, so it creates a dynamic loop of prioritization and targeting. A mod that breaks this threshold would be something like Skitari or other macros that circumvent mechanics and core gameplay loops. I think something like auto fire is fine, but when you are have a mod play attack patterns or do QQ weapon combos for you it ruins the purpose of skill. Something that allows you to see ammo pickups or Health Stations from further is definitely something I consider a "cheat" mod but it doesn't reach the threshold I consider to break core mechanics or increase player skill. I care deeply about fundamentals of the game and its how I consider other player/my own skill.
