If you can't see THE problem with the whole scheme (i.e., pre-potting was a bug that never was patched), then there's no discussion. You'll just try to justify a faster kill (and did), using any means possible including exploiting and cheating.
It just shows what raiding has become, exploiting and cheating for cheat sake (and none of them are even ashamed). All that elitism gone to waste. They'd compromise their own morals/ethics for that faster kill, for faster loot. -_-
