Eldar mostly, seeing those small and thin space elves trying to bring down a Chaos Space Marine only to be cut to pieces by my chainsword will be most exquisite
I will kill the xeno, the heretic, and the witch with equal zeal. Though, Eldar make the funniest squeals and wails when they die, most satisfying!
Probably Space Marines and Orks. Orks 'cause they will probably be the squishiest, spess mahreens 'cause it's going to be the go-to faction for 90% of all the people who are getting into Warhammer because of this game and will probably be the ones I'll be fighting against the most. Funny enough, those factions are probably going to be the ones I'll play until the guard becomes available.
the Eldar, those obnoxious, uppity, self absorbed, stuck up space fairies. bloody xeno scum, Emperor help me I hate them so much even more than Chaos
Taritor scum indeed Burn the Heretic Kill the Mutant Purge the Unclean so Chaos-Orks-Eldar in this order
