My favourite class is deffinitely Soldier . So much funny stuff to choose from, and basically all of it deadly.
Classes I like to play are Engineer and Covert Op
My most unfavorable classes are: Field Op (I don’t like playing it at all, it’s damn hard to use support against good players). Ammo isn’t as valuable as it might seem - ammo cabinets… Being ammo factory isn’t such great adventage as health factory.
Anyway, I think ammo producing is the most “stable” field op ability. Artillery and airstrikes may be big and noisy, but it’s gambling. In right hands mortar is much more deadly, but not without Fieldop support.
Spam Ops are usually biggest teamkillers.
Medic - it’s so easy to play with it’s no longer funny. My former favourite class. Medics with good kill2death ratios no longer impress me, because it’s no challange. Medic can fight in most stupid way and still live. It’s not like I have to value my every hitpoint nor ammo round. Still, I play Medic more often than Field Op.
:drink:

:blah: 
) and I want to win the map, that’s why I usually play the class most needed (Medic, FieldOps or Eng).
