So how will you use her?
for me when I play zerg I prefer large masses of weak units to swarm my foes so my Kerrigan builds will be one of these
1 Tank: In this build she will be the spearpoint of my assult. I will give her various heath and dmg upgrades. Her job to take out foes that would give my zerg masses touble as well as breaking open tough defenses so my zerg can swarm in and destroy it from the inside out
2 Taskmistress: this this build I will give her abilities that buff my other zerg forces. To termpoarly make them faster and stronger. That way she can give my zerg spear the exra push it needs to overcome foes
