So bear with me....

When a level 10 player says "Fire magic is too expensive!", we don't worry about it because we know that it's just a new player problem, and soon a couple hundred councils won't matter at all to him.

When someone says "i'm having trouble leveling, there need to be more pigs!" we don't worry about because in a couple of hours he'll move past pigs and it's not a problem.

Similar to those two examples, part of the current problem is due to 1) An influx of people from steam release 2) The game isn't finished and we don't have all the zones. Adding instances isn't a fix, it would take months to do in the current schedule with 3 developers. But in that same amount of time we'll see more new content, the player bump from steam will even out and people will be into more high end content, and this problem will mostly pass.

So yes, it may be an issue for some people right now, but they will be past it pretty quickly, and eventually the game will add more areas.
