U could just read some o the comments in this thread there are plenty of answers for ur question.
Well first impressions got fortified. The Game looks really good. I like the art, i like the gameplay and also im into the Lol lore enough to enjoy also this part of the game. Overall it looks just awesome. Now with the new patchnotes and the upcoming nerfs for rasa/ledros/elusive/fearsome it is looking like riot knows how to handle balancing in the future. (those were rly strong cards that got a nerf that is fine and not exagerated). I guess LoR is my new CCG!
