Tactician with 2 lone wolf characters (the only way I've played yet) is pretty good.
It is quite a lot harder than EA but certainly doable. You get the extra AP, Vitality and points from Lone Wolf which offsets the enemy increase.
Could be Lone Wolf is OP but that is another question - the combination with Tactician is fun and works well. Lone wolf on Classic would be a joke.
It is long winded though - Flenser I had to flee and the Dallis fight (in the fort) took more than an hour and a half to grind them down into giving up.
