WISOTT. Each LL starts with 3 extra starting units in ME except for Nakai, who just has 2, Kroxigors and Sacred Kroxigors. Other LLs have much stronger starting mix such as Sigvald or Imrik, so I don't see why Nakai can't have a third unit. My suggestion is a unit of Razordons given they're in his dlc.
That is all.
