What's your favorite class(es) in multiplayer?

My problem with the Indra is the bright bullets in the scope. I'm photosensitive, and have to be careful of such things, the Sovoa in Andromeda is a damned good example of a gun that can instantly end my play session, be it on myself, or a team mate. Granted the Indra isn't as bad (Particularly when used by others, I suffer no ill effects then), but it's still not a good gun for me to use.

As to an SMG to speed things up? That would be the Tempest, the trollstore has not been kind. For the VolSent, I find his defense and crown control is unrivalled, adding more in the form of a gun just limits his offensive potential for me, that said, his "offensive potential" is currently an Argus, which I find a hell of a lot better than the Valkyrie (which the trollstore also saw fit to give me early on).

I hope my seizure reference didn't come across as inappropriate - I have nothing but sympathy for your predicament, as my mother has suffered from migraines all her life and I too can be prone to occasional difficulties. I appear to be becoming much more sensitive as I get older, with textbook visual migraines (no pain) afflicting me quite regularly these days. On the positive side my arthritis is well under control, though I remain a human guinea pig when it comes to Crohn's Disease management and research.

On a much more serious note, I found each and every one of the guns in Andromeda could instantly end my play session. My partner wouldn't believe I was playing a Mass Effect game when she heard all the pew-pew-pewing going on. True story.

And don't get me started on the Valkyrie - the RNG Gods have had such a laugh with me and that gun, on every account. It's not a gun for people who can't be arsed trying for headshots, and I am quite proud of my scrub status in that department. I'd still rather use it than the Argus though! 

I also forgot to list the Smashguard/Lancer as one of my favourites, though I have to give a shout out to clips7 for that because every time I play him it kinda feels like I'm moonlighting in someone else's shoes. 

Typhoon Volus Sentinel is the best choice. Mini Spitfire is also pretty Rambo. One or the other! But the Typhoon has a more manl..uh...Volusy dakka 

I feel that the Argus is criminally underrated. Yes, it has a kick to it, making reliably headshotting difficult, but if you can control the recoil and land those headies. Things melt fast. But, with the Valkyrie I get the melting with a lot less hassle. Just my 2c.

Recoil Dampener and Piercing mod makes the gun viable on anybody, not just a Turian. Recoil is more than easy to handle than (but yes, it does kick a little too much without it). For me, the Argus blooms after the burst is fired, meaning the bullets fly straight on the initial burst, Valkyrie always seems to bloom between shots, meaning the first hits, the second goes a little wide, not really a problem against a charging Brute with that big HS zone, but when trying to hit enemies further away? Not so good. Again, not sure why, everybody else seems to have the opposite experience with both guns, so who knows.

Asari Valkyrie/Claymore/Piranha
Asari Vanguard/Raider/Claymore
Asari Adept/Carnifex
Turian Sentinel/Lancer/Wraith
Claymore with Claymore occasionally switched up with the Claymore.

Volus Mercenary Sentinel.

Agreed.

Also it's not everyday, you get to see someone like me who can, hard carry gold/plat games with the VMS.

He's not the flashiest, but he's my favourite Volus overall that I have the best success with 

I'm going to bite. Because you see... I am one of those people.

I mean, how do you even play this guy? Good gun can make pretty much any class good, but the difference between most classes and this little tub of lard is that most classes have some sort of offensive power. But this chubby? He has a decoy and a drone. The latter is at least somewhat offensive, but yeah, I would expect it to carry me through Gold, much less Platinum. And the former? It doesn't even live up to it's name, most of the time. At least in my experience.

So enlighten me. How am I supposed to play him?

Fine. I'm gonna give it a shot... on Silver first, because I'm a scurb

But I want a build. I presume no fitness? Or maybe a 3/5 split between Decoy/Fitness, similar to SE?

Here's a caveat: once I'm through at least three Gold games with this guy, I reserve a right to mock him mercilessly. I may like him and I may find him amusing, but not worthy of further attention. But if I honestly dislike him, I will say it plain.

There's no rule that says everybody has to like every character. For me, I like to skip passive on him and take a Saber (hence why I don't play him much on PC), but any good gun that you are good with will do (Particularly Wraith/Saber/Valiant/Paladin/etc), though I will also note: The aiming angle can take some adjustment, don't be disheartened by it. Some skip Fitness, some split Fitness/Passive, some Fitness/Decoy, there really isn't a wrong build for him. Basically the pattern is pet (reload cancel with it if reload is needed) -> cloak (see previous note) -> other pet (note applies to all) -> other cloak (reload cancel for days), and of course, lining up shots and popping heads along the way. As to the cloaking, if you're not being hit, it wont help as much, but the point is to force an aggro recalc, this doesn't dump as badly as Winfiltrators because pets have a slightly higher priority, and if both are out, there's a good chance you'll even cause aggro to shift from the other players to the pets. And as always, an ear out for team-mates in need of shields is always something a Volus should do. Also good for those crazy-infiltrator style revives, but even better at them because you can heal the revived player. Quite possibly the best all-round team-mate to have.

EDIT: Ninja'd with a good build (even if it varies in a few choices compared to what I would use), I will note that for other Volus, 5a of Passive is better than 5b (5a still boosts shield boost, whilst boosting the other powers, in fact, a VolGuard can get decent damage from Biotic Orbs).
