wow just played a game where a guy seemed to be all over me with burrowed roaches and kept sniping my collosus so I switched to double chronod robo immortal production with stalkers from gateways... Eventually he sniped my main nexus due to some careless observer placement and I managed to take out some of his roaches... Thinking I'm way behind, I just go for the kill with maybe 12 immortals and 12 stalkers and a few zealots against maybe 60 roaches... and WIN... Easily with still 1/2 my army leftImmortals seriously are amazing against roaches... I definitely need to use them more against Roaching zergs
Yeah people forget that immortals have awesome DPS, but they need to be well backed up as when outnumbered by quick attacking units they still fall fast even with the 10 max damage. Also don't forget to always have an observer available for your army vs burrowed units!
