Up For Anything is good. Crazy range, good magazine size, good impact, and Persistance makes a noticable difference in landing headshots. It's got two of my favorite scopes (the first two in the tree, whatever they are called) as well.

I have vanguard marks and commendations burning a hole in my pocket. The only Vanguard weapons I have are Another NitC, and TFWPKY. Neither I really use.

Are there any other vanguard guns worth getting? I'm just looking for something that would fit in as a contingency in case I need a legendary in the slot instead of an exotic or something. I was thinking of the fusion rifle possibly, although I rarely use those in PvE.

Same thing for Crucible gear.

It has the best perks I've seen on a Vendor roll. Slow charge time is compensated by the fact that it's basically a legendary plan C; huge range and impact with perks. But I understand you don't use AR's ;)

I hear LDR is nice too.

Up For Anything is a pretty decent autorifle. I don't use autorifles much, but when I do I tend to favor the slower-firing, heavy-hitting versions (like the old Shadow Price Vanguard rifle, or the Grim Citizen Crucible rifle). Up For Anything isn't quite as slow and stable as those, but of the current crop of autorifles it's the closest I've seen.

LDR 5001 is a very good sniper rifle (and I don't even like sniper rifles, generally). I have one that's arc, like the vendor sells, but it was a drop so the perks are different. The one the vendor sells actually has armor piercing rounds, which would be very useful even if the gun generally sucked (which it doesn't).

None of the others really jumped out at me. The stats on Plug One:1 actually look pretty good, but I'm not sure it's worth spending marks on a solar fusion rifle when you probably already got a Murmur for free. I have a Time on Target pulse rifle but honestly it seems pretty meh to me. It didn't really do acceptable damage until I maxed it.

LDR is great. I got "The Supremacy" from the queen's bounty way back when and the stats are almost identical -- much better than anything else pre-expansion overall. Same impact as icebreaker, better stability etc.

I got a plug.one as a drop and it's almost always a 1-shot kill in PvP, assuming I'm giving it a slight pre-charge time.

If you're into scout rifles, the badger is a decent option.

from the other vendors I've not used a ton of things... I'm missing my deviant gravity MG from dead orbit. It's got a high impact and a decent firing rate. The range perk helps a lot too. I'd prefer that over the against all odds that I have now.

Another NITC is a good one to have--it might be best to wait and see what rotating perks are on there, though.

Up For Anything can kill anything.

LDR, I guess.

Secret Handshake is good too.

And if you can, get Harm's Way. Excellent Machine Gun.
