Not sure yet but I seem to have an issue. I just got ttk and hit lvl 40 so I only used her a couple times in pvp but I dont seem to be getting the full fire rate its slow no matter how fast I pull the trigger. I equipped high caliber rounds and so my thought was that perhaps they slow the fire rate but not sure when I can test the theory. Its like a suros auto rifle, pooof pooof pooof instead of pop-pop-pop you know? Slow and it gets me killed. Maybe I need to uninstall ttk and reinstall since it seems I get a stall in action once in a while and it stops to load for a second. Idk. Feedback would help.
