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

...refreshing.

Prob Vanilla Human Engy or FQE. As long as Inc ammo isn't picked there is no cheese to be had and no weapon bonuses to speak of. Good platforms overall. Melee KroSent is a blast to play.

If going for pure output, the two Vanilla Turians are great.

I detest Infiltrators and broken or distracting powers (Cloak, Snap Freeze, Flamer) and will avoid these kits 99% of the time.

I can't choose between the two fat Turians and the Cabal which I like the most. As TTT once said, you can't choose between your own children.
After that the Kroguard (you always remember your first ... platinum solo ), the ACA, the Geth Engie and the SalInf.
Huge fan also of the blue girl Val, vanilla humans, QFI, scums, volus ... Yep, still love this game after all these years.
Overall I'd say there is only one kit which I dislike, I'll let you guess which (hint - broken controls).

On-host Juggernaut.
Widow QFI.
Mantis GethEngie.
Saber QSol.
Cabal.
Ok, I think I'll stop now, most of them are my favourite for the duration of the match that I am playing with them
Off the top of my head though, these would be among my most favourite, however, I am more partial to themed matches than just playing my favourites or the bests.

In other games I normaly can't realy deside but in me3mp it's easy:

FQE even better with Claymore (or Graal on host)

Warlord. I don't even have to look at the screen. If I feel like actually using my brain, either the demolisher or batarian soldier.

KroSent/Claymore
QFE/Claymore
HE/Carnifex
TSent/Phaeston
Shadow/Piranha
Justicar/Acolyte
BatSol/Raider
GE/Saber
QMI/Valiant
HFA/Wraith
SI/Widow
GI/Jav
BF3/Claymore
AHI/Talon
VorSol/BPP
BatSent/Kishock
AA/Suppressor
VorSent/Venom
BatDept/Harrier
FQI/Claymore
AIU/Crusader
VolMerc/Falcon
Jugg/PPR
KroSol/Graal
VolEng/CSR
Paladin/Paladin
Fury/Tempest
TSol/Eagle
ACA/CSMG
DAI/BW
BatGuard/Raider
Valkyrie/Hurricane
SE/Scorpion
Havoc/Lancer
KroDept/Executioner
HMI/Mantis
MQE/Arc Pistol

That'll do off the top of my head. There are undoubtedly more, certainly involving a Claymore here or there. I have a lot of melee-focused builds and I don't really play Infiltrators all that much, but I really do like trying to find the best character for each weapon, often with one eye on lore.

Adepts in general are my favorite because Fury, Cerberus Defector Adept, Human Adept, and Drell Adept are really high on the list for my favorite MP characters.But I like a lot of characters:

Fury (Crusader/Venom)
Cerberus Defector Adept (Hornet/Acolyte)
Shadow (Talon/Carnifex/Piranha)
DemoGirl (Typhoon and Scorpion)
Drell Adept (sniper and acolyte)
Human Adept (Hurricane)
Batarian Adept (Venom)
Turian Soldier (will try anything)
Destroyer (Typhoon and Venom)
Qurian Male Engineer (Arc Pistol)
Turian Sentinel (Valkyrie)
Human Sentinel (Piranha and Acolyte)
Valkyrie Sentinel (Venom)
Qurian Female Infiltrator (Crusader)
AIU (Crusader/Claymore)
Cerberus Defector Vanguard (Talon and also best Vanguard of all time)
Batarian Vanguard (Raider)

I pretty much like all the MP characters in the game to varying degrees minus Talon Mercenary, Turian Engineer and Ghost. But these are my favorite. Outside of the top five, the rest are in no particular order. Fury is definitely my favorite of all time.

I always have a hard time deciding things, and I haven't even played all characters yet, I have yet to experiment with different setups and weapons, but... for now:

Phoenix Adept, Fury, Drell Adept, HAdept, Batarian Slasher, Krogan Soldier, Batarian Soldier, HEngineer, Geth Engineer, QFE, Vorcha Hunter, HSentinel, Vorcha Sentinel, Paladin, Turian Ghost, Shadow, QMI, Batarian Brawler (with Piranha ), plus in general all asari.
I love the Volus as a concept, but I only played them on Silver so far.

That's a no-brainer, Reegar AIU of course!

Ahem... I have made it a point to find at least one build + loadout for each kit that I can handle and enjoy on gold, with the only exception being the Talon Engie. That said, CSMG vanilla HSent is my go anywere, fight anything kit: sturdy, mobile, does well on any map against any faction.
Some classics that I find myself playing over and over are Valiant QFI (headshots all day), Crusader Huntress, Lancer TSent, Novaguard (in a team of good primers).
Other loadouts I enjoy busting out include Carnifex GE, Vindicator TGI (hits a lot harder than you'd think), Graal KroSent (melee), Saber Destroyer (when I want to switch from Typhoon gameplay).
But really, I try to rotate among all kits to keep things fresh, and I will play toons I feel I have been neglecting - though fitting with the rest of the lobby is always a consideration for me.


(I usually put Eviscerator, Katana or Graal on the AIU )

Ksssshk, I give you 3 tries.

I need four.

Kssshk, wroooong! It's the Adept God!
