Do I care? .....absolutely not. I think they are silly and never understood why Ubi included them in this game.
....scratch that. I do understand why, because they wanted to cater to the casuals who like that sort of content in these types of games. I just don't like it myself and feel it's more appropriate in a franchise like FC or WD than TC/GR.
I prefer to customize. The thing I hate about a lot of the signature ones is you can't use a suppressor. I also don't worry about firepower because I always enable Tier One mode anyway and max the damage stat. The better non sig weapons are powerful enough until you get a ways into Tier One, then you can ramp up the damage anyway once you get the resources.
Agreed. In a game where stealth is so important, it just seems incredibly stupid to throw all these weapons in with no suppressor option. Not to mention, most of them are trash compared to the custom build ones. Makes no sense whatsoever.
The only one I really like is the Los Extranjeros BFG. Awesome power and fire rate, suppressor ready, and not hideous like the Desert Tech HTI.
Overall, signature weapons suck out loud. Wish I could get my money back on that really cool looking orange themed sniper rifle, can't even remember the name of it anymore. Can't equip a suppressor. Useless.
