Yup, no Dindrenzi Tier 2.
Taking the Terran Escorts does a few things:
1 builds a huge PD+Shield Mountain no one wants to waste Torpedos on.
2 makes you an extremely hard boarding target
3 creates a zone enemy SRS do not want to approach
Of these, #1 is the least important to Terrans. And as pointed out, it just forces the Torps elsewhere. Now, if you make elsewhere a PD mountain (which is what I did against you) then it works well.
Finally, there is one benefit to all escorts: another small target. If you're opponent has to choose between shooting Escorts and 3 Frigate Squadrons, he's more likely to make the wrong choice.
