Power Creep for the win!

Just wanted to comment on how great power creep is. I used the new Nightmare campaign as an excuse to go back and master the Nightmare bosses I only completed. I want to thank this Reddit for the strategies. I had 4 nightmares I haven't mastered and thanks to last stand roaming warriors (still no native last stand :( ) and overstrikes I was able to destroy these nightmares without a sweat. When they first debuted they were so hard.
