The tags currently are very limited. There is a lot of focus on how to get the sheep going again. My understanding is when the population does start to do good it expands. When it bumps up to domestic sheep the herd is exposed to disease which can spread rapidly through the population with a high mortality rate. It's really a while other can of worms. The same is true for moose populations. I'm sure someone smarter than me can list the reasons, but the bottom line is the populations are not thriving in the way they were expected to when the point system was put in place. There was a realization that the current model for tag allocation is broken and needs addressed.
I really do appreciate that people are upset that the oppertunity they thought was there is being reduced, but the allocation system was broke and the best time to fix it is today, not in five years when it's even more upside down.
