The problem is players greed.
Not just in Bg's but for farming for materials like skinning, herbing and mining.
I never grind any longer than 3-4 hours in an area for materials, yet I see the same players there everytime I go there farming 24/7 and they spam the AH with everything they have farmed screwing up the AH prices.
I don't feel sorry for them if they get banned because they simply deserve it.
Maybe a ban might teach them not to abuse it....
I agree. Posting 1stack of stormvine 50times really gets anoying.
