So I just happened to be on YouTube and did a double take when I saw COH 2109. I AM SO GLAD TO BE BACK! Anyhoo, I saw Sentinels but I haven't yet understood how they work, which brings me back to the old days of Blappers. Are Blappers still a thing? I used to have a 50 Fire Blast/Energy Blapper...was looking to roll something different, yet effective. Any suggestions?
