- Newborn would be the weakest stage, in health, armor, and damage; its one measly spike is also easy to dodge for Marines on the move. - The 50% mature Hydra could either shoot 2 spikes shotgun style (with slight spread, same base 20 dmg per spike), or allow up to 2 targets at a time to be targeted. - The Mature Hydra would be very deadly if all 3 spikes connect.
The reason for the idea is that I find Hydras are very expendable right now; there really isn't much incentive to keep them alive except for increased health and armor with maturity. A Gorge would basically digest a Hydra just to free up the cap, and throw up a new one elsewhere. If Hydra's effectiveness increased over time, I hope this change would introduce more decision-making:
Should I eat my Mature Hydra and move up... or should I keep it to defend the RT, while putting up my third Hydra? What if I need 2 of them and my 1st is too far away to be digested? Hmmmmm.
