I'm sure there will be a few groups ready to pvp as romulans within two months time.
The Somraw, K'tinga, D'Kyr, D7, Kumari, Xindi carrier, Xindi escort, and the T'Varo are all older than the Constitution Refit and yet they are tier 5. The Constellation is made up primarily of Connie refit parts and it is tier 5, there is no logical reason whatsoever for the no tier 5/6 connie rule.
TOIVA, Toi Vaxx, Toia Vix, T'vritha, To Vrax: Bring in the Allegiance class Toi'Va, Ti'vath, Toivia, Tia Vex, Toi'Virth: Add Tier 6 KDF Carrier and Raider. Tae'Va, T'Vaya, To'Var, T'Vira, To'Vrak: Give us Asylums for Romulans
