Ah, after over 40 minutes, I finally got a team together where someone didn't leave to run through the entire Fire Temple level. I've gotta say, this is the hardest Moldorm in franchise history. Granted, I don't think Moldorm has ever been difficult, whether it be in A Link to the Past, Link's Awakening, Four Swords Adventures, or A Link Between Worlds. It was just annoying having to navigate a small place with two other people and having Link dash around like he's being oven roasted when he gets his butt burned.
I doubt I'll be playing the game much with randoms when it actually comes out, but using the emotes has been a lot better than I thought it would be. We can communicate pretty much everything we need to through this simple tool. That said, I still think Nintendo needs to make efforts to improve its voice communication tools next generation.
