Hey Gunter,
Yes I thought of this, but then I would either have to a) host a download of that for everyone I play with, or b) tell them/explain to them how to do it, and they all complain about excessive mods and going through an extensive list before we begin, which makes it take forever to get started playing while everyone is trying to get on the same page mod-wise... My goal is to bring to my community a short and easy mod list, so that we can achieve a lot of variety in weaponry and gear, while being able to jump into an operation in ~30 mins or less.
At this point, HLC has so many variations on weapons and does a great job at filling the void where the vanilla weapons fall short, that to me it makes complete sense to have one comprehensive download (such as Massi's Nato Russian pack, or the new Community Upgrade Project). I think these mods would be a really popular weapons pack compared to the rest out there--high res textures, great audio, detailed reload animations, all of these weapons feel like they already came with vanilla Arma 3 IMO
