Because you aren't using those mats does not make them useless. If you don't want those items, don't loot them. Again, the point to the cows was to provide mats that are unobtainable through normal means. Up until the cows were added, there was no way to get the high end mats that they drop at all. There are engineering recipes that use some of those "useless" mats that you don't want, for example, that up until now, were very difficult to get.
