so its clear from the trailer that rieklings are in the game
we also see a tusked bristleback, so those can safely be counted as in

but about the 'riekling raider' [riekling riding a boar] itself...
do you think its 2 separate creatures, or just 1 model like they were in bloodmoon?
do you think a riekling can just go up to a boar and mount it with some new new animation, or will the raider class be a model all to itself that is 'connected' to the boar?
