Vader's suit is not nearly as bulky, that isn't even a fair comparison. And actually in the EU, Vader went through great frustration due to the lack of mobility his suit caused. He had to completely alter his fighting style.
Not The Last Jedi but still a new important Star Wars release, 15 mins until Rebels season 4 premieres in the U.K.!
Well, each Grey Knight is a powerful psychic (and note that "powerful" is referred to the 40K magnitude), and they use Nemesis Force Weapons. Their armour is warded and protects the wearer from psychic attacks. Plus, ranged psyweapons.
Are you sure? Spoiler I am successfully derailing this thread, The power of the dark side is nothing, compared to the grey one!
True, but please consider that no one is more accomplished at derailing threads than I. (although that isn't particularly a good thing)
That just initiates and activates my anti-AoS defense protocols. And said person will rue the day they derailed my thread with AoS. After all, ripping on AoS is my very favorite topic of discussion! (I just withhold it for strictly defensive purposes out of respect for other people's hobby beliefs/enjoyment... like a Jedi of sorts)
