Right now, with the 50% limit, I find I can
take a Mark I Battlecruiser...say...Hood,
and refit it into a Mark IV Battlecruiser
with 3x the firepower and 3x sensors quite
easily...
If it was THAT easy IRL to refit ships,
why did the Royal Navy bother building
all those Dreadnoughts from 1906 to 1914?
You have the
Dreadnought single ship
class in 1905,
Bellerophon class of
3 ships in 1906,
St. Vincent class of 3 in 1907, etc...
I think limiting Refits to 30% - 40% of the initial cost of a ship would help prevent
the constant refitting of ships into new
superships and force players to actually
construct new ships instead of constantly
upgrading 20 year old spaceframes
