Hive and synergy with eggs
Hive is by no means unplayable, but it clearly lags behind the other factions. This is primarily due to its very difficult early game. Even when playing optimally, we will suffer losses. A minor mistake can cost us as much as half our army.
The easiest way to fix this would be to buff level 1–3 units, but I think I have a better idea. Some Hive units could receive small bonuses when eggs are destroyed. Our insects would then go wild. For example, the Parasite and Locust would get bonuses to speed and initiative, and the Hornet to defense. Additionally, the Locust could have the ability to jump on eggs to break them and trigger effects.
We could play around with this mechanic more. For example, Hive Mothers could receive bonuses when eggs hatch, and certain upgrades could receive a debuff when eggs are destroyed.
I think this would add depth to the gameplay without significantly disrupting the balance. The player would have to decide whether to sacrifice eggs for valuable speed points to reach enemy shooters or to hatch the larvae instead.
