I think there should be 'X' tournaments, where (kinda like the summon X Quest,) the cards you draw are randomly drawn from every card in Tyrant, with the same amount of rares and uncommons ect.
It would add a lot more risk into joining a tournament, and you would always be surprised when you looked at your cards.
@haloronin, and the rest of everybody, it would be way to much to change things already in the game that drastically. They're only going to add new cards, or add new upgrades, they're not going to change the ones they already have.
If you're going to get rid of crafting, make sure faction wars give more money, and maybe, reward the completion of a quest with a chance of getting a warbond or two.
