I don't think our Rom/Rem toons should have to start at 0 in the Reputation system. After all, we find the planet, survey it, and help build it from very early in the story arc. I can understand grinding Omega/Nukara if one chooses to, but I think you should give a Rom a bone, if you know what I'm saying.
Maybe we could start at Tier 3? All the hard work of the story arc has to count for something. And it is our technology, why do we have earn it (or at least work as hard to earn it)?
I like this idea as well, but i will play Devil's Advocate.
It's probably good that they don't do this. Because it would give Romulan players a BIG advantage in terms of character development. I mean, even just tier 1 means that...hey, playing a Romulan means you wouldn't have to grind out the first tier.
If it was a larger bonus, like having access to the whole thing would be an even larger boost, and a major disadvantage to non-Romulan players.
On the other end though, it'd be kept fair if Fed/KDF players got a head start on their own rep. In this case, Omega rep would be the most fair option, because the Federation and Klingon Empire have been fighting against the Borg for the longest time, compared to the broken Romulan people, who cannot muster that strength as easily.
So a Romulan toon would gain a big jump ahead on Romulan rep, while a Fed/KDF would get a bonus to Omega. A fair exchange, if this was to happen.
