I take it the tanks were in siege mode which would explain why it was close (before the nerf you would have lost probably due to tanks splash obliterating hydras).
Additionally brood lords would have provided great support as thors are not really effective against them and you did not say he had vikings.QUOTE]
yea they were in siege mode and it was after patch so i didnt quite get obliterated and their werent to many vikings as he wasnt exactly investing in any one thing he seemed to be getting abit of everything, i also had around 3-5 mutas which i used to take out the sieges first up, after i had distracted the vikings to go into ground mode with my hydras... also i found a neat trick that most people already know, use brood lords on a mass of marines or something with sieged tanks nearby, the sieged tanks attack the broodlings that spawn and deal a decent amount of damage to the marines, i beat 70 marine +10 marauders with 5 brood lords, and the tanks as well

then my hydras cleared up the rest, so hydras are good just got to use them in conjuction with other units usually
