You probably already know this, but TI is disabled in FFA.
I don’t use UAV/motion sensor because I’m bad at paying attention to the map. It probably shows in some of my videos. I pretty much ignore it about 80% of the time (especially if I’m moving about a lot/quickly) The other 20% of the time I’ve made use of it passively (I’ve noticed activity on it and responded accordingly) rather than actively relying on it.
I know that my claymore is often rendered useless against people who use hacker, but I use it anyway for the chance of getting the people that don’t. It also gives me a better chance of survinging when I have to become vulnerable (such as driving an rc-car or doing something else that takes my view away from my person) by placing it near to where my body is. Also you might be surprised how often people who are using hacker get killed by one of my claymores. If their attention is drawn away from the red claymore silhouette by, say, being fired at, they will often completely fail to notice it.
Also, if not using my claymore to protect my vulnerability while doing something out-of-body I will often leave it there and go off somewhere else (move about the map as normal), so a hacker who sees and therefore assumes I’m somewhere near it, will often be mistaken. On the occasions where I am near it, they will probably have to shoot it to deal with it (I place it in such a way that they are unlikely to be able to get behind it to hack it)… which in turn alerts me to their presence.
I’ll try the Famas.
edit: P.s. do you have any videos of your gameplay? I’d be interested to watch.
