And this is EXACTLY why I've argued that leech should not be brought over. Because as it is now, Federation Romulans will come up with innovative, creative builds, while Klink Romulans will just run to the leech and rebuild their cookie-cutter prefab ships.
Their "cookie-cutter" builds are tried and tested. They are also superior to anything a Fed-Romulan can come up with while compensating for the lower base power levels.
Innovative and creative builds will not be as effective as the current builds. People seem to think there is a lot of depth to this game. This is far from the truth.
