May I propose an idea for the merch store?
First off, I didn't know exactly where to put this, since I couldn't seem to find a dedicated commerce board, so if this is in the wrong place, please let me know and I'll move it.
And the TL;DR, for those of you that like them: Jewelry.
Hear me out. My favorite champion is Braum. His kit, flavor, and personality really resonate with me. And a while back, I thought it'd be pretty cool if I could get his shield/door as a charm or pendant of some sort to put on a chain and wear around. I've seen a few other third-party people selling metal or clay charms of other champions' weapons, and I thought it'd be a really neat thing to add to the official store. I'm not sure how feasible it would be, with so many characters to think of (how do you pick which ones are included? If you plan to do all of them, how do you decide which ones go first?), but I bet I wouldn't be the only one who'd be interested in seeing things like Draven's axe(s), Katarina's dagger(s), Diana's sword, Leona's shield, etc. in some wearable form.
As for what they'd look like... I think metal with enamel is pretty standard for charm things like this (though I'll be honest, I'm very much not an expert). I like the idea of them just being miniature versions of the items themselves, and not just plain metal colored or something. I'm not picturing them being terribly big or clunky, but I think that's at least in part because any jewelry I wear tends to be pretty minimalistic and understated, just a personal preference. I feel like pole weapons like Wukong's or Nami's staffs (staves?) or Nidalee's or Xin Zhao's spears would lend themselves well to being attached horizontally to the chain, so they'd have a link to each end and be a part of the necklace/bracelet itself, instead of hanging freely like a pendant, if that makes sense. In the case of champions who have multiple weapons, like Draven and Katarina, they might even make good earrings. Mages would be pretty difficult to include here, but you might be able to do it. A bright blue glass bead for Ahri (I confess I'm a sucker for pretty glass) or Karma's Mantle of Decorum, or something along those lines.
I don't really expect any Red attention for this. I don't even know if you can take merch suggestions from the boards (I know other departments like Narrative or the actual champion designers can't take suggestions from the players because of legal reasons), and if you can't or can't say, that's fine. I know you guys read a lot of posts, even if you don't respond to any of them; I just thought I'd throw it out there in case you were looking for new ideas.
(Second suggestion/opinion: I had always envisioned the poro plushes being fluffier, a bit like this or this. I don't know if you'll ever update your current official design, but that's just my two cents. My mom always says free advice is worth what you pay for, though, so take it as you will.)
