If we completely forget about Tensers, a Blade has still decent THAC0(with the help of his 10 offensive spins and Potions of Power), and is still better than the F/M due to UAI and traps. A F/M cannot equip Montolio's cloak, or Carsomyr, or the Purifier, or the Chaos Blade, or a Holy Symbol(for str and magic resistance bonus), nor can set 7 Time traps in the battlefield area before the spawning of enemies. In fact, the Blade is a weaker version of a F/M/T, and not F/M.
