Raptor all the way, unless the team would desperately need someone who is flexible.

I'm definitely going for tactical marine, as it allows you to have a bit of all the action in one class.

As a big Thousand Sons fan, I have to go with the sorcerer. I'm actually really excited that I'll still be in the thick of the fighting and not just a glass cannon. As for secondary, I'm running havoc. Someone has to scare away tanks...or carnifexes...

Havoc/Beserker and terms if they get added.

I'm likely to switch it up a lot in practise, but I'll probably be mostly playing traitor.

Raptor and the Havoc. Raptor for those times when I need to appease the Blood God, and Havoc for those times when I just want to support with heavy weapons.

currently the tactical, although I'll probably hop onto the Raptor train at some point. Hopefully I do get my Noise Marines at some point, I'd love to drop loyalists with my WUB WUB WUB.

personally i would love to play more with the raptor, but i can never seem to be successful with that class. i imagine it i my lack of skill rather then a flaw though it does seem like the raptor has less health than anyone else.
