I'd be overjoyed to see the samurai/swiftblade/blademaster archetype be fufilled in WoW, but I feel like they should be in mail or leather armor, and exclusively use two hand bladed weapons (mainly swords, but also axes and polearms). Arms always felt like it was supposed to be butchering enemies with an axe, not slicing their enemies to a thousand pieces using a longblade. Hopefully, survival has a quick enough rotation and the option to mog their spears into swords/axes for me to fufill that fantasy for me.
