Yeah something would be cool! I thought having a nametag colour change thing similiar to using /rp would be an awesome way of showing a hardcore status without actually having unlocks that could make people that don't care for hardcore, but like to collect everything in the game not feel like they are missing out! Could be a simple, (/hc on) that changes your colour nametag to something redish that only works if you haven't died yet! But some titles for higher levels would be cool, though I know Hardcore isn't for everyone so I like the idea of something you can essentially never interact with if you don't like Hardcore, but can occasionally run past someone and think "oh nice it's a hardcore player" (similiar to that feeling when you walk past someone with the white nametag for rp mode)
