So, thoughts:
-With relatively small teams, it makes an outrageous amount of difference if one team has an AFK or disconnected player. Like, automatic-loss level of difference. There needs to be some way of preventing this.
-It is 5000 veteran points to get a loot chest that, from the sound of it, is probably just a consumable buff? That's 20 wins. 20 wins to get a probably-disappointing consumable? That new set had better be amaaaaaaaazing.
-I don't get how barrel roll works, or is supposed to work; it seems like a cool idea (I love "alter the map" kinds of abilities) but in practice it seems to be either buggy or just completely terrible.
-Those gripes aside, this is a really cool new feature. I imagine that this map, being really very simple, will get stale pretty fast, but the options to add new adventures should be a lot of fun. I might be in the minority here but I'd love to see some cooperative, players vs. computer npcs adventures, with longer more complicated maps that you have to fight your way across.
