I was getting bored of Tharja/Ephraim/Hector/Priscilla in TT since the former 3 are my arena core. So now I'm running Reinhardt/BLyn/Hector/Priscilla, and it is glorious. Rein and Lyn just tear through the entire map by themselves with sheer awesomeness. Lyn doesn't even have a pony skill to buff Rein, he's just that good. Hector is an actual god who can lure, counter, and kill almost everything if I have trouble approaching. Priscilla makes sure no one has any problems. Hector in the final map is an issue, but Lyn can chip away at him safely, Hector can tank him, and the AI is dumb enough that I can usually nuke them before they swarm me. Perfect scores are easy, and Hector/Lyn is nearly canon.
