I always found it wrong to move the idea of a main antagonist from aliens to a new nation. Gallia as a whole was an unnecessarily big addition to an already big community. Instead of creating a new house with lots of new things, the development could've been (should've been from my perspective) focused on improving the dynamics of the world we already have. You can do limitless things in the current game world without Gallia. Just like doing something WoW did , a la Cataclysm sized RP change / environment change would give uber life to this mod, as well as countless new things to discover in an ever familiar environment. And since we were already based in this part of the game, it would be a rather fluent and flawless transition. This, I told to Igiss back in 2009, it is 2012, there wasn't anything positive to change my idea regarding Gallia in this 3 years.
The new Gallia ideas are promising, I am hoping to see more.
