Hawkian, thanks for helping me out! First Nightfall was pretty sweet. I didn't know about the experience boost! Seems like its the first thing to do each Tuesday. I got a Legendary Scout Rifle. After my random Crucible MIDAS drop earlier and a Cryptic Dragon the day before, Destiny seems to be suggesting I main Scouts now haha, that's 3 in 2 days.
One thought after this experience: I love me some shotgun madness in PvP, but they're so hard to use on endgame PvE. Since enemies are aggro as hell and have that karate kid melee modifier, getting up to shotgun range is very dangerous. Snipers are great for some situations, but I feel like Fusion Rifles are just the all out best option.
The only Special/Element I don't have is an Arc Fusion, and I feel it placed me at a disadvantage for this Nightfall. My Arc shotgun is a pretty sweet Legendary I got from the Raid (Final Verdict), and when I finally got into a position where I could use it I wrecked shit. It's just such a gamble that I think I would've gotten twice the kills had I carried a Fusion.
Maybe this is general knowledge by now but being my first Nightfall it's something I'll bear in mind for the future.
