Gonna bump this thread cuz it's a good place to talk about what we would want from AoC DLC. I have a wishlist of things I want to see.
1. Linkle. I want her to get in so badly and I wanna see her in Champion blues. She was my favorite character to play in the first HW and I just adore her. I'd love to see her in AoC somehow. Also it would fit because Link's HW tunic, the one with that sweet blue scarf, is the reward for 100% completion. They already have a connection to the first HW that way.
2. The Master Cycle Zero. I'll take it either as a fourth weapon type for Link or a Divine Beast stage. The game already made plenty of references to the Champions Ballad so it would make sense to see it. Plus Monk Maz Koshia is an optional playable character, so the fact that the cycle isn't already in the base game is really surprising to me.
3. I wanna see a DLC storyline on Link's family. They had the perfect opportunity to introduce them here and they didn't and I'm really bummed about that. His dad is a royal guard captain, for crying out loud!
4. Robbie and Purah would almost certainly be DLC characters. They already have models for a presence on the map and they do have a basis for movesets. Purah carries a blue flame and Robbie has that ancient tech backpack thingy. They could totally do it and I'd love it. Also I get the feeling we're gonna see Kilton in DLC because there are sidequests that talk about Fang and Bone.
5. I wanna see DLC storylines focusing on the origins of some villains, too. Sooga is implied to still be alive even though he doesn't appear after Astor betrays the Yiga. He shows up in the true ending credits. (but then so do the future champions and they already went home.) I'd like to learn more about him, and he seems like he'd be a more fun playable character than Kohga. I also want Astor's backstory really badly because his character profile says he's from a "certain small town in Hyrule". WHICH TOWN? YOU CAN'T JUST SAY THAT AND NOT ELABORATE!!!
6. I want alt outfits!!!! It's not fair that only Link, Zelda, and the Champions can change their outfits! I love alt color schemes. C'mon Koei.
So yeah there's a lot I'd love to see out of DLC. There's a lot they could do, and they'd only need to add new points on the map to do it. That'd be really easy. I'd totally shell out for all that stuff.
