I think this is a good place to post this...
Aka, i didn't check, but I bet u missed one thing talking about 4 hydras vs 1 BC. when BC kill hydra, damage of hydras reduces, doh.
cooldowns 15 and 30, so ok, BC one shot, hydra two shots:
without upgrades (to kill BC = 500/7 ~ 72 and to kill Hydra = 80/25 ~4)
4H > 1 hit vs BC > 8 hits +8
4H > 2 hits vs BC > 16 hits +8
4H > 3 hits vs BC > 24 hits +8
3H > dead H vs BC > 32 (or 31 if BC shot first) +8 or +7
3H > 1 hit vs BC > 38 hits +6
3H > 2 hits vs BC > 44 hits +6
3H > 3 hits vs BC > 50 hits +6
2H > dead H vs BC > 56 hits +6 or +5
2H > 1 hit vs BC > 60 hits +4
2H > 2 hits vs BC > 64 hits +4
2H > 3 hits vs BC > 68 hits +4
1H > dead H vs BC > 72 hits +4 or +3
...lets say BC started shooting few second earlyer and saved himself 3 more hits from hydra:
1H > 1 hit vs BC > 71 hits +1
1H > same vs BV > DEAD BC !!! =]]
so in conclusion 4 hydras kills bc with one hydra left with full/almost full HP. Results will change depending on upgrades mostly, if BC and hydra fully upgraded, hydras will do same damage, but BC will do 25+9-3 (dmg+upg-armor) = 31, so in that case hydras will die in three hits, even 25+6-3 will kill hydra in three hits (28x3 = 84). now price:
BC 400/300 ...right?
Hydra 4x 75/25 = 300/100
)
...i dont understand how BCs can own hydras?? even without swarm and/or plague? ...and yamato wouldnt help much anyway.
And by saying this counter that, I mean spending about the same amount of money...
BTW, terran will have BC only in mid or late game, and if zerg is still alive, he should have many hatcheries and it should be very easy to mass hydras fast...
...AKA, just dont say anything about combining units ok? this is BC vs Hydra
