Maybe a series about countering meta decks. Things like counter deck ideas, play strategies, tech cards, and times to try to climb with counter decks?

She's gonna level absurdly quick, seeing how the reforge minions cost 1 and 2 and then she reforges. I don't think she's overpowered, but she is really strong. 

Also, I think she'd work well with viktor, because of get fired up and the discard draw card, as well as her doing a better job of creating spells that you actually want to play. 

Karma, base shyvana,, base maokai, and heimerdinger would like a word. 

Literally every competitive card game boils down to just buying the best cards and decks. Every single one. At the very least LoR is more willing to change what those cards are and, as a result, the game has by far the most diverse and balanced metagame of any of them, and I've played them all. If the game isn't for you then that's cool, but you can't use something every game does as a knock against specifically this one. 

More to your actual complaint, however, I do agree that some of the popstar animations take too long and I do hope they either allow us to turn them off or shorten them somehow. Maybe only show the animation the first time the spell is cast?

Either way, if you're uninstalling then have fun with other games.
