Daomei (atys)
The question Salazar raised was about competitiveness, not ethics. There is no competitive gain in shooting down unarmed diggers quite similar to a sniper's shootout which clearly is far from bravery.
If you think this, then you are not the type of player who likes pvp. Simply because "killing" diggers and so on can be a part of pvp. Why should I let an enemy dig some materials to build armor and weapons? If you want to be better regarding equipment you have to hinder the opponent to get supreme materials.
