81 Horms is a lot! Since you are over 2000 pts, I would suggest two-FOC to move the Troops Tervigon into HQ - no need to buy Termagants for him then.

Other suggestion - if you have more points to put anywhere, put them in a few Venomthropes to give cover saves to those big Horm squads and Tervigons.
