First impressions are stunning visuals, but at a cost of loading times and battery life. There is a setting "lobby power saving mode", which is great, but it doesn't help with load times
PVP is typical 5v5 Battle Arena. However the game isn't newbie friendly. You will get matched with people who have 200 + matches experience right from the start.
Cash shop is mostly cosmetics and unlocking heroes faster
Overall it's a beautiful looking game, but that's about it. A far better experience was another NetEase MOBA Extraordinary Ones (if you are looking for an Anime themed MOBA)
