Since i posted the screenshots of possible new mounts and also the cheerleader miniature, i checked out some more figures from the table-top game. I really have to say that Mythic did a nice job of creating the looks those "originals" have into the game. Looking at a bunch of those miniatures shows some very cool war-boars, that actually look like you could fight with them. So an upgraded model with those long tusks would look very cool. I like those a lot, looks like they crossbreeded boars with other animals.
I only found one picture of those mentioned "magical machines", the Ironback Boars and have to say i don't really like their look. Then I'm rather giving my vote to the earlier mentioned "classic" looking WAR boars. If you want to get an idea about some cool looking Orc armor, dig through some of the miniatures... some very cool stuff. Although WAR already has some cool Orc armors, its just that they're only used on NPCs and a lot of shields or the Darkpromise gear just use placeholder models at the moment. Let's hope that changes soon...
This one is for scribbler: I found this thread about a guy creating an Orc Boss miniature, while the Orc is riding a hybrid between a Rhinox and a Boar. Check out the pictures in that thread, hes posting all the different stages. While I'm not into miniatures myself, i found this a cool project nontheless.
Talking about WAR, how cool would it be if you could also dye your mounts armor?
