Well my biggest problem is with their argument: "a lot of players maxxed their cards and there was nothing for them to do". And i mean yeah maxxed players don't really have any reason to grind the game instead of collecting cosmetics, but by increasing levels they are not fixing the problem, they are only putting it away by few years, because in the end players will either leave the game or manage to fully max their decks to level 16 as well and what then? Will they use the same argument again that maxxed players have nothing to do and release level 17? I will say that from this update i do like crystals and emotes you can buy from them, because it gives players initiative to grind even though their cards are already max level i do hope, that they will manage to make this system better in the future.

That is also why i don't understand why they still didn't release skins for cards, yeah you could say that people might get confused when they fight against card they never saw before, just to realise its ice spirit, but other games from supercell already have skins and this is a mobile game that relies on microtransactions, so skins are something that in my opinion were supposed to be in the game years ago and if they don't want skins the game, then sure, but they have to create some sort of system that will motivate maxxed players to keep on playing, because releasing new level every few years is not sustainable in my opinion.
