The people most opposed to the change are the ones who "suffered" most from being UA bombed.... which does suggest that there is a bit of a pitch forks and torches thing going on. The internet is great for people getting outraged on behalf of others.
Imagine it would be illegal to punch other people in the face no matter what the circumstances are. I am sure people who enjoy boxing would not appreciate that, yet people who only got punched in the face out of nowhere in a shopping mall would be in favor of this new law. So yeah, people who enjoy playing the UA bombing game dont like the removal of the UA bombing game. In a surprising turn of events, people who dont like the UA bombing game do like the change. So it is about which side is larger. And we both know the answer to it. So if you and some folks want to UA bomb each other, I am all for a mechanic where you can do just that. Without annoying the overwhelming majority of people with absolute impunity.
