They said there will be ways to show our "veterancy" and I was curious about it..I think it should be cosmetic like for orks; they get bigger and for chaos boyz; they get moar spikes?

Chaos will most likely get flayed human skin capes, marks or icons of their patron god. Perhaps terminator armor and special weapons. So, actually it really is more spikes.

+1 for awesome ideas.

It could very well work like Blacklight: Retribution in that you are given in game points to buy equipment, weapons and customizables. So it could be the more you participate in the game, the more access to different equipment you have.

I don't think it'll be the level progression thing as in other MMORPGs, but I've heard that your shooting range and spread could be better as you increase in level.

There's probably gonna be more equipment available as you play.I'm just saying that there also should be racial cosmetic items like skulls on spikes, relics etc. to show off your achievements or veterancy at the game.
