I'm not opposed to elves with hammers. I remember reading the Silmarillion and looking up the Book of Unfinished tales where Gondolin had both warrior groups with clubs(!) and smiths in all black armor fighting with hammers (and they were the good guys). Super-niche, I know, but the idea stuck. Plus, White Lions had huge axes and that's another weapon lots of people wouldn't associate with elves.
But, yeah, I get the feeling everyone else is struggling with.
Curiously, I don't hate the helmets. I still mostly find the proportions of the giant bull thing just in some kind of uncanny valley of body proportions.
Maybe its presence feels less weird if I just think of it as essentially a treeman. Big stompers aren't entirely alien to WH elves, I guess.
Still, I would've liked to see a dragon. Maybe with a future Tyrion-centric release.
