I like the new Colletion (Crafting/Components) but the new Battle Arena forcing us to to battle against people is just wrong, you could have ADDED that feature not take the last one down, it was perfect for us to test our decks and try and create new tactics. I say give us back the old Arena Battle because this new one is not necessary, if people want to fight against each other they join Tournaments!
