What was you easiest auraxium or hardest?

Being my only Auraxium, I guess the M18 Rotary is both my easiest and hardest by default.

I'm not particularly working towards any. I just play what's needed at the time and hardly play as much as some people do...

Hardest: Needler for the mozzie.
Easiest: Marauder for the Harasser. Took me 2 hours.

Hardest: Solstice SF ... ~3200 kills, 25 to go ... this evening ... (I'm sure there will be a patch this afternoon ruining the medal for it ... again)
Easiest: Nova - Shotgun, kill and get killed

Easies; Phobos
Hardest I don't really have one, but one of the NNG chaps got it on the flare gun, I cried getting to fifty and this dude has over 1000.

Easiest: Supernova PC
Hardest: Nemesis -that launcher has no auraxium medal, it simply ends after the gold one (rage).

Wow that's crazy. Serpent was my first and I wasn't even tracking
it or trying to Auraxium it. I mostly ran as Engi, but LA for towers.
I didn't even use SPA at that point, just the foregrip and IRNV and
then I just ADSd people in the face. It melts HAs with shields up.

Nova was my second, and 95% of that was with Slugs from a mile
away. Best Battle Rifle in the game, although now it has tracers so
it's not quite as easy. 4x Scope + Extended Mag = Win

SAW was definitely the easiest with the TMG-50 right behind it.
The Ursa was fun for my playstyle, and I'm slowly walking up the
Flare now. I doubt I ever Auraxium the SVA-88 as it just doesn't
work for me. I've also never (ever) fired my Orion other than in VR.
BR72 and i've never used it.

Hardest (and most enjoyable): C4
Easiest: Any double-advanced laser guns (I play Vanu so - VX-67, HV-45, etc) // or pods.

Going on 10+ Auraxiums with infantry weapons. Vehicles only adds about 3-4 more for me. I think I would had much more had I stopped using the Corvus, HV-45, and VX-67 earlier.

I think I might be one of the very few with as many Corvus kills as I do (4k+). If there's anyone else, holler.

HE Shells in the first 15-20 days from game release date was the easiest ever.

I can still taste the tears.

Easiest: GD-7F - For a long while I used Engineer and LA almost exclusively.
Hardest: EM6 - Every time I got this weapon figured out, SOE went and "updated" how it behaves.

Well my first was the Mercenary so I guess that counts as the easiest

Hardest, haven't got it yet but I think it will be the Mag shot

Easiest : Pandora (full auto shotty)
Hardest : Soltice Burst (burst carbine...though it's slightly better than it was pre GU08 or GU09)

Pandora with slugs on my Engineer. Pre-Shotgun Slug Nerf.

Still the best weapon for cqc engineers.
