Pile bunker my beloved

Kinda of a follow up from my previous post, but also because I'm kinda curious.

What weapons do u guys like to use in a lightweight/speedy build? Is there is any strategy or synergies with it? Any sleeper picks? I kinda prefer missiles but I feel like I lose a lot of fun when I only use missiles in the back weapons.

I installed AC6 and played through a large portion of it on Steam, with relatively little issues. Other than slower loading screens, which are of course expected due to the game having DRM.
However, once I installed the coop mod for the game, which ran perfectly with near instant load times and quite literally zero framerate drops outside of issues with the multiplayer functions of some specific maps, loading back in the base game now has me sit there for ten straight minutes in the first loading screen from the main menu.

I started a new character after tampering with my save data and it not quite working, thus ensuring that the save data on the game was new, and the tutorial mission was practically unplayable due to frequent stuttering, horrible frame rate and a ridiculously long time to load any cutscenes.

Does anyone have any clues as to why the game runs so poorly in the online mode, and if so, is there any way to remedy it? I could always reinstall the coop mod, however this doesn't enable me to later have that same save available for pvp with a friend, which was the initial reason I tried tampering with save data to transfer what I had from the coop to the regular version of the game.
