I probably DID get lucky, but I know I wasn't confusing them. Wolf was one of my most-prized units in my last PT (Savage Mode). He was never killed and never went under 15 HP below his max out of the 50-something he had. Sedgar ended up being a front-line defender, though. He didn't have much STR, so I just got him to raise in DEF and RES as his most important asset. He almost died in a few battles, though. Good thing I had Merric and Lena to heal him.
