Well as DA player It's damn good question. And Hard Work for Developers
So I want to try all base classes (as Codex said) but i like tactical with plasma gun
Also I prefer to use Machines so I think pilot of Predator or maybe LR
Bring my brother safely to front and cover them with mightiest weapons that our Legion have
Agghh I love World of Tanks ))) Bring DA TANKS FOR DA BOYZZ!!!

i played assault marine mostly in EC, but my favorite is tactical. i'll play them all, but i'll start with tactical for sure

Im going to lend supressive heavy fire support to my teammates. i love taking supportive roles in mmos. so^^

An apothecary, hey, someone needs to patch you guys up

I'll be giving them all a go, but I like the idea of getting in enemies' faces with a Thunder Hammer and Storm Shield.

Devastator, my duty is cover my brothers with my Heavy Bolter!

Close combat defense & fast attacks against enemy shooters. Going Assault with Power Sword and Plasma Pistol.

ill be doing pretty much the same, as my Chapter Master, is armed with a storm shield and power halberd.

This game is going to be, AWESOME!

Such a tough call! Assault and bring the Emperors Wrath to the Fallen. Or an Apothecary. What's the road to Terminator armor?
