Never had a problem personaly.
Just dont spec your escort out for OMGZ PEW PEW LAZORZ and you will be fine.
As claydermunch said, Polorize, Jaming and ablative hull will all help you live that bit longer.
That said, we are not tanks.
And again for anyone that missed it.
WE ARE NOT TANKS, WE ARE D P S.
We kill stuff, FAST.
Our job is to get in, chew the rear off that enamy cruser and get the hell out again.
You WILL die, LOTS.
Thats just the nature of being the DPS ship.
However as I have said, there are many many things you can do to mitigate your dieing so much.
The main issue is the fact that all ship and weapons have same range. Typically in a MMORPG a glass cannon has range on his side and gets a couple shots in before the target can hit back. Also the crowd control types are the enablers of the glass cannon to keep alive, which don't exist in space combat.
