During these times of game testing, Principal Lead Combat Designer for Star wars: The old republic Georg “Observer” Zoeller, is closely monitoring the beta gamers play, to solve problems with faction imbalance. If you the launch of World of Warcraft, most american servers had an over wait of Alliance players, and the European servers an over wait of Horde. So far it don’t seem to be a problem though. But as we all know things might change at launch. Here is his forum post: 3hp3
“During Game Testing, we’ve been watching closely which class players decide to play at various times – such as:
The first time they faction balance, but the cycle of news releases to our community does not seem to be a significant factor at all. If it was, well, I don’t think the community would take it all that well if we started delaying availability of information because of this. ”
Since faction Republic stories if there are twice as many Imperial players as I won’t encounter them anyway (at least not in a story context).
I will say this though. Just because two factions have roughly the same number of players doesn’t mean that the factions also have roughly the same number of PvP players. And player distribution during testing probably isn’t a very good indicator either. But I’m sure that BioWare is keeping such things in mind.
