I've been playing since near release, and I love infiltrator. I know how to play it well, but I always feel like I'm not dealing enough damage fast enough. The rifle you start with is really great, and I've nearly maxed it's damage. The problem with it is ammo and reload time. I understand it's necessary to give it a smaller amount of ammo and slower reloading speed for balancing reasons, but with enemies constantly popping in and out of cover, it's certainly not a DPS weapon. (To me, anyway. I often find that I'm just about to line up a shot, and the enemy dives back into cover, I miss, and I have to reload.)
So, my real question is, what rifle and what armor are the best for an infiltrator character? I imagine using armor that boosts damage (If any armor does.) and combining it with a fast rifle would make for a real badass, especially if you are using maxed tac. cloak. I rely on my heavy pistols a lot, because of ammo capacity and high damage, but it's not good for long corridors or cross-map firefights.
If you could tell me where to find/buy the items, I'd appreciate it, but that isn't necessary. Just the names are all I need. Thanks.
