Ah... I understand your view now... Sorry...
Just to clarify: Do you think that the high difficulty of arena is more important than the fun factor and that it isn't how impressive the achievment is but how difficult the arena is?
The difficulty is a secondary thing. As long as the arena works as a competition for the decks, there should be clear rules on how your deck is scored. Right now there's a straightforward system for rewarding wins and punishing losses, and a stupid, fuzzy adjustment thing that changes your score based on what the people who played against your deck felt like.
I'm all for rewarding originality, but it has to be through a solid ruleset that tells you up front how your deck will be scored. In the current system the players you get have almost as much of an effect on your scores than the deck itself, because everyone has a different idea on what's fun or original. Like I already said in another thread, personally I thumb-up everything because why would I not give people free gold when it costs me nothing, and I think the whole system is retarded anyway. I'm pretty sure there are also people who thumb-down everything just because they can. The idea of rewarding originality isn't necessarily broken, but the way it's currently done is.
