I don't understand people... I just gave my opinion, and they down vote my comment, lol. The new arena isn't that bad, the arena is more competitive now with this new ranking system.
Seriously... I don't understand why people want a trading feature. It would mess up with the game. Imagine, people would create multiple accounts and they would buy a lot of packs with the initial WBS, everyone could have ALL THE cards in the game. (Sorry for my bad english)
Thank you very much! :)
