Also even if its called "Swarmborn" i think that you should completely embrace the starcraft clone aspects and replace enemies with protoss and terran that fight each other and have different building mechanics (terran no creep can build everywhere, protoss needs to build next to pylons) this way you'd no longer have these awful area of influence around enemy bases, rename souls as biomass. Going this path instead of the fantasy one would make this very eye catching and you'll have a lot of players + 2 iconic factions you'd be able to play so even people who don't really like swarmy factions can be attracted.
Sorry for the bloat hopefully you'll really consider going the copycat route.
