You just like starting arguments don't ya Horner?

They've stated companion's aren't going to function like MMO pets. In that, they aren't going to make up a portion of your own character's abilities (where an MMO pet class, the pet would be a large part of the class)

There are only 4 classes per side (just as a side note) not 5.

I would love to see an Engineering pet class (deploying droids and other tech/gadgetry) and a Teras Kasi artist - a martial artist, unarmed class....

Ahh what could have been.
