Honestly, Cryptic seems to be missing the point of "Cruisers" in STO. Yes, they are massive. But they still have the same impulse engines as every other ship. Instead of nerfing the "turn rate" through the floor on every cruiser, i'd rather see a reduced maximum speed, with escorts having the highest speed and turn rate, and science ships at a more balanced speed/turn.
I tend to stay away from any ship that has less than 10 in Turn Rate. Everyone who successfully flies a slow moving brick, will probably tell me to equip a Turn Rate booster console. Problem in doing so, is that I also reduce my survivability which is kinda the defining feature of STO cruisers.
As for the Romulan page... PURE SPECULATION. People seemed to have quickly hopped on the bandwagon that it's a potential new playable faction in Season 8. For all we know, it could just as easily be the "Season 8 Site" which is yet to be revealed, or the content is simply a new Romulan-themed episode. My honest bet, is on a Romulan Lockbox, just to milk some extra quick cash.
