Well considering the weapons are not that DRASTICALLY different from each other (i mean except some vehicles and their guns and ES guns) but still i tried a while ago, just doesn't do it for me and i don't have the money or time to invest in new characters. The Skyguard is kinda boring to me, don't know. Could try the last one.
I kinda ignored the directive thing when introduced because i didn't get any credit for all the things I had already done and didn't feel like redoing. But when I realized I was close to a few of them, I've started to pursue them anyway.
i am pretty bored by the game right now, waiting for something fresh like new weapons or the promised tank secondary changes which would make me play again ironically enough, smedley promised that no new content is added until bugs/performance are fixed. well, TWO MONTHS PASSED and not much happened. even worse, lots of devs were fired and the remaining ones seem to get less stuff done for sure not a doomsayer or something but this is probably the worst state the game is in. lets really hope the upcoming PS4 release frees up a bit more resources for the actual development
You don't like infiltrator..But you really should try some session of stalker. It's a very different gameplay, you can lone wolfing and try different pistols/implants (special regard for safe landing/medic kits) It can be really hard/or rewarding, and it can waste a lot of your time just to kill one guy . You can change the difficulty if you choose Xbow/oneshot knife or just take an underboss. you can trap enemy mines with your own mines or just throw an emp...
New weapons? I don't know, i'm looking forward to the resource revamp (probably somewhere around 2019) new weapons are just new toys that we don't really need, and they will only slap a different skin to the almost same weapon just with tiny changes added to them. But the sec. guns, i look forward to that.
