Faeria is a very solitary game in its current state, unless you go to a third party app like Discord. It would be awesome to at least be able to spectate public live games, even if you can only spectate Practice Pandora and Casual matches. I personally don’t care about anti-cheating measures and don’t think it’s a big problem, but you can anonymize the matches or delay public spectators by a short time (5 min) if it helps.
Chatting with a party while spectating together is also a great social activity and opens the doors for other fun things, like guilds.
I remember Clash of Clans had a way to watch public replays and vote on them (or something), and that was entertaining and helpful for new players. You could speed up the replay too, which I would highly recommend in a game that requires Faeria’s concentration (lots of thinking time on every turn).
Actually, replays in general are an extremely important learning tool. I have no idea why Hearthstone has yet to implement them. They already know how important they are from Starcraft.
