Nope, it's not useless at all.
I started playing the game with my brother on Tactician mode. I'm using a Lonewolf tank, while he's using a 3-element wizard with Bairdotr by our side. It's been a blast, there's enough moving components to make the fights interesting and the extra HP/skill points are proving to be really useful, especially on the early levels.
Haven't tested out with 2x Lonewolves, but I'm sure it's still great if you're familiar with the game.
