Terran have the advantage mid game though with strong MMM before there are a lot of and Collosi range
True but as soon as storms comes out (whether they go 2 base HT or not) you're basically screwed and any Toss that uses FFs properly is going to easily survive.
Like last night I had a game on Metalopolis. Was 3v2bases I went in, got a good engagement and thought I was going to decimate what he had as I was doing one of the builds I've seen Polt do. The guy storms cos I didn't realise he'd got HTs as he seemed to have gone the robo route first and my army vanishes in 2 seconds.
I can pull back during the storm but that just lets everything but the HTs attack and I need to keep kiting so that more storms don't come -_-
