Social dawinism. That's what the game is about.
The "great"/"elite" people will be trying to find ways to get a "legal" advantage over the norm - that's what the whole game is about. Finding a new weap that's better than your enemy = you have an advantage over him. It's the same.
But that is part of the game.
Playing more than one account is using artificial means. For example I could bite trhough the power cable in an enemy GM's power station and cut him out of the game, hardly ethical though is it...and certainly cant be compared to finding nice equipement. Finding better items, as the heroes of the Warhammer Universe is all part of the game.
IOd certainly saying paying more money to have an advantage over normal players isnt...and it smacks of insecurities over your ability to play and fight vs the normal player.
