I agree with all points as well
As a PS4 player I did not see Purge Ram being used very much. Plasma Ram was of course the most used - and this was typically used as a sacrifice or trade attack.
A 20% armor boost may have made the original Purge Ram viable ( low damage but at the cost of disabling)
I would suggest bringing back the standard Purge Ram but add the 20% damage reduction bonus when it is activated.
I have never seen or used Blast Ram in action and this type of bonus could make that module viable as well.
Just thinking of the possibility of disabling a ship and then the next goal possibly being for the Ram ship to escape sounds quite interesting.
Nothing to add about the Corvette notes. Again just an excellent job of breaking everything down, Thank you
