Dust is the Dark Souls of FPS's. Prepare to die and rage.

Meh your like 2 years late to actually be good at this game, YET again i might be wrong if you get the FOTM and be a skrub.

Your choice padawan

In a scale of gameplay from easy to most frustrating for new players eith an example or two:

Beginner: Destiny
Novice: planetside 2
Intermediate:
Advanced:
Expert:
Nightmare:
Dark Souls while smashing your nads with a hammer: DUST 514

This game is FPS hardmode on top of a few core issues. Newbies run alongside closed beta vets and the disparity between newbies and vets is almost akin to a child with a butterknife trying to fight a spetznaz.

You can't get good by FOTM chasing. As soon as the FOTM changes, the platform of false skill you were standing on will crumble under you, and we'll all laugh while you fall.

I've played for over 3 years now, and I've learned that the best way to do it is completely ignore what's OP and what's UP. Don't chase either, don't run from either. Just stick with what you like, because its performance could drastically change with a single patch.
Mass drivers in closed beta started out as garbage because their hit detection was broken, so tryhards wouldn't touch them. Next patch the hit detection was fixed, and the tryhards cried for a respec to flock to them.
