Im always up for some games, need all the practise i can get! what race are you?
Luxotican.425
Yeah, Hydra/Roach is much stronger now due to the range buff. Puts T1-T2 combo's into a bracket that can actually be on par with the other two races.
Best thing i could do really is watch you play some.. throw some replays up if you like.
check this one out, quite a decent game. ZvP

Gives you some idea of how powerful roach/hdyra/ling is... also how important flanking is.
Mutalisks. They shouldn't really be used as a mass attack group albeit extreamly powerfull, because the lack in ground units leaves Zerg vulnerable early game.. Just attack them earlier and they'll have no chance. IIRC its about 8-9 minutes in.. just before their spire pops out
I use mutalisks for early game harassment and contain.. which then allows me to drone spam and either pump more units, tech up, or expand. I only ever use between 6-8 mutas, anymore in my honest opinion is a waste.
The counter for them is Thor's & Marines as Terran works the best. mix in a few hellion for his zerglings.
Protoss should think about going stalkers with sentry guardian shield -OR- Pheonix.
Stalker / sentry is not a mass muta counter. It doesn't work. You need approximately 50% his muta count in Phoenix really. And you have to micro real well. Thing is you have to know he's going mass muta so you can have enough phoenixes up in time. Also if you can hurt his gas, that will cripple his muta production.
