If I was you developers I would throw this data in the bin. There is no way in hell you can balance this game through this poll. You can't get around the bias no matter what you do. By trying to remove the bias you will also remove objective data. Best to stick with what you have been doing and tweak until you are happy.
I'm a 1hander/shielder and guess what; I voted to buff 1hander/shielder, that makes me human and wanting to gain an advantage. I did this believing that 1handers especially are pretty much balanced.
In fact I think you have done a good job balancing this game except for throwing. You killed throwing. Logically if you buff throwing, then horses should get a buff also.
Maybe what others have suggested. Look at the individual weapons in a class instead of the class. Some weapons are just OP. Others just crap.
So fuck this data, no good can come from it.
