Okay, I've been noticing early each week they'll change the class models in some way.
For example: The current build I was playing last night, has the TR HA looking like this.
Where as the first build had the TR HA looking more like this.
Clearly more badass and 'advanced' in appearance. So they've been quietly testing all different models for the classes throughout the last few weeks. So there will be some visual progression represented in our characters, although currently I'm not sure if it battle-rank, cert, or shop tied.
I haven't really paid much attention to the models of the other classes and factions, anyone else noticed any changes?
I've just managed to compare the NC and VS engineers aswell.
The current build as a more basic version of the class models, much like the TR HA.
