Even though I haven't used them that much, the Drowning Doom is a favorite of mine. Debuffing is always awesome.

Ironheade seems much easier to play after playing through the campaign. I need to play some pratice rounds with the other 2 to try and learn the units.

I havent played any muliplayer yet but i plan to but the drowning doom seem like you could do alot of damage with all the debuffing and the tainted coil of course are beast with they're hierchy stuff and being able to spawn units on the battlefield but i think No matter what i'm gonna like good old Ironheade always cause they are straight up aggressive damage all the way!

ME and my friend have done loads of online games, only won a few and they were as Ironheade, so I picked them  
@bonbolapti: Lionwhyte faction would just be Ironheade... But with Glam Metal Colours?

I really like the Tainted Coil.  Spawning units right onto the battlefield is a huge tactical advantage.  More importantly, I can't spawn HATE CAGES with any other faction. 
 
Finally, Doviculus is awesome.

"I default to Ironheade becuase I've played the entire game with them.. but honestly.. I wish there was a Lionwhyte faction :( "

Ironheade is the easiest faction to play as.
 
I feel Tainted Coil is too powerful.

Tainted Coil. So much sexual innuendo, so much fun.

I prefer Drowning Doom, its an awesome faction but I cant seem to find any matches online, Ive been searching for 10 minutes and I havent found anything

tainted coil ftw, i used to like ironheade but i think the coil is way better. skullrakers can kill fire barons in one hit with ts double team.

I've only used IronHeade so far but I'm going to try out Tainted Coil tommorow and see if I'm any good with that faction.

Drowining Doom, but I suck as them, so I play as Ironheade, since I'm only playing for achievements and won't play anymore after that.

I mostly stick with Ironheade as fast, heavy assault is what I'm tailor made for, and I'm not sure my strategies would work best with Doom and Coil. 
 
On the OTHER hand, Tainted Coil is fast becoming tied for my preferred faction. They're healing system is superb, the Hierarchy is really easy to understand, and I won a stage battle very easily by expanding my army to huge proportions and distracting the enemy, while I sent one Bleeding Death straight to the stage, where it demolished it just before it keeled over.

I played online once. I was Ironheade. They seemed alright.
