Void talismans are not really
an issue - Many ways to counter them, Kutte is right. Problem in the arena for me are things I can't control but they spoil my enjoyment; being attacked more than you can possibly counter without spending insane amounts of ironite, is the biggest frustration - like Slauki says. Makes it difficult to go away for a bit and not be able to log in, then see you lost 200+ points. Like going for higher ranks is more an exercise in buying power and free time rather than playing skill or team composition, and actually loses you ironite.
Part of me is glad for a few Eric Cartman's who will help fund the game in this way but I'd prefer an environment where everyone felt that spending a few dollars was worthwhile, and that they could realistically climb the ranks.
