That was a very interesting breakdown on Escorts and their capabilities in the hands of a tactical captain. I agree with almost everything you said, and what I don't agree with isn't worth bringing up. But... it's a DPS based game (as PvE goes anyways)... and what do Tactical captains specialize at? Tearing faces off. What are escorts good at? Tearing faces off. Apples + Apples = more Apples. Until PvE end content changes away from pure DPS (which is a good way for PWE to lose money, so it will never happen), tacscorts will always be the most effective ships for PvE.
My fleet mate flies a Science officer in an escort, and he does great in PvP and PvE.
Yes, he can put out great damage, and he can subnuke his target. Very important in PvP and PvE (especially in the Hive STF on Elite).
