Balance Implications of Everyone Using Larva

I’m making a melee mod that allows players to choose which units they’ll have available to them for the match. Part of this is that everyone has a single shared tech tree/economy, which uses larva for all unit production.

I know there are bound to be balance issues with every unit spawning from larva, but I’m not good enough at Starcraft to really understand what it will mean.

Will Terran and Protoss units be superior to Zerg units since you won’t need multiple production buildings to make a bunch of them at once?
