I'm not exactly new here, but considering I don't rp on this board very much. I won't be voting, but I figured I could the least present just my own opinion. The idea of Joining factions is nice, and all that jazz. But when it comes down to it, its up to the members to make it work. If you have some members that aren't fully committed to such a thing, of course, the idea as a whole could collapse. So once again, its up to the members to make such a faction thrive. By which, many of you I'm sure already are aware of.
There are merits with both plans, IO particularly I'm not an entirely big fan of the fall of the Republic story arc, simply because I think there is already a faction with the "Rebellion" title in name and definition among the ranks, if I am mistaken, I truly apologize. In regards to fighting on for the Galactic Republic, I like it. Just for my own reasons of I've always like that there was a Galactic Republic here, it makes me think back to the EP 1,2,3 and then to EP 4, with Obi-Wan's quote. "For over a thousand generations the Jedi Knights were the guardians of peace and Justice in the Old Republic, before the dark times, before the Empire." Not to mention, I always thought it would be cool for any Jedi Master to go before the Supreme Chancellor or a Sith for the matter and just be like. "In the name of the Galactic Senate of the Republic, your under arrest Chancellor, err...I mean Sith." Haha!
Moving on.
Merging factions would be cool as well. As it was stated earlier from what I read, if you have such unity and join allegiance with each other and you could become the ultimate power in the galaxy. Do we as Jedi strive on power, no. But, alas, you can see my point. Good stories will come of this, and as far as a new surge of activity is nice. We can never be sure for how long. Yet once more that remains up to the member to strive for such an achievement of honor/chivalry and whatever we could hope to achieve by forming into the Galactic Alliance.
Once more, I thought I would just put forth my own opinion on the matter. The choice is yours.
And remember my friends, that no matter what happens.
The force will be with you, always.
