I think the CoP changes are a good thing. If you did the missions when they were tougher, all the credit to you. But you have gotten your reward for doing it, its not like SE are making you do it over. This just gives other people a chance to get something out of CoP.

I have been playing for about 3 years now, and I still struggle with CoP missions. I will be glad for these changes, might give me a shot at last.
