I won't yammer on about what everyone else has already covered lol. I just want to throw in my two cents on the arena update since that seems to be the largely overlooked one.
I absolutely understand the frustration with afk grinders, it makes the game way less fun if everyone is just afk, but I also feel like having an ensured reward made things feel a lot more open and accepting of new players. It was something I always made sure to tell people, to not worry so much about whether or not you know what you're doing because there's a guaranteed reward for you no matter what, to just do your best and to have fun! And I feel like this makes the arena a little less welcoming in that regard.
While there's certainly mostly bots playing right now, there have been matches completely full of actual players, and I feel like cutting out rewards for some of them takes away from the welcoming feel of the experience when you spend 20+ minutes for nothing. It stings to go up against 9 other players and walk away empty handed, when you had already lost and done poorly.
Perhaps a better way to handle it would be to have something monitor participation? In that you get no rewards if you never put anything into combat, perhaps? Sure, people will still abuse it to try half-heartedly, but it takes away from people clicking ‘play’ and then leaving the tab to do something else by forcing them to at least do something.
I don't think it's inherently a bad update and I understand the reasoning behind it! I just feel that it makes the arena less welcoming to more inexperienced players and can result in people who are already struggling feeling even more stung and less inclined to learn how to play. I absolutely agree that something should be done to address the afk problem; while I get why people are doing it, the arena is meant to be a participatory minigame, with absolutely no requirements any which way to play it. It makes the experience less fun for the people who actually do want to play when no one else is even doing anything, then it just becomes a game of ‘sit and stare at the screen for 20 minutes’. And that's not fun, and drastically ruins the enjoyment of people actually playing for the sake of a few people getting singular tickets without doing anything.
So I'm glad that the situation is being addressed, really! And I don't feel like this was a bad way to go about it, by and large it's not going to pose a problem for anyone beyond the afk grinders; few games reach full capacity and most people (edit for clarity: i say this based entirely on what i've seen in the arena channel on discord!) can claw out of 9th and 10th place even if they don't know much about what they're doing. I just feel like there are better ways to address the problem that don't open up the risk for new and inexperienced players feeling stung for the sake of being new. :)
