I bet you complain when the guy in front of you at McDonald's finds an onion ring in his french fries.
Part of me wants to point out that we should take this conversation down a notch so we don't get to the official forums point, and part of me just really really loves this line. lol
Well you have to compare the price to the one of equivalent value. It is a no-commitment 1 month fee with 8 chars per server, which is $14.99. Though I can't see the purpose of having multiple characters either. I'm typically someone who enjoys making alts and it seems that this game won't have a purpose for it. So I might just do the entry cost ($12.99) myself. It depends on what you can experience the game has to offer through alts. The last game I played with a similar class setup was The Secret World and I still made one alt to play a different faction. See anything like that in this game?
Interesting point on that is I was hanging out in Teamspeak with one of the guys who wanted me to pick up this game and another friend who, like me, will be new to the game come ARR. The friend of mine who is a legacy player was telling us about how he was going to get to reclaim his character and full items. At first, us two newbies were a little shocked, my 2nd friend moreso than me. Our "legacy guide" was quick to point out that we can't think of this as a new game, that this is basically an expansion and we are just joining late. Hard to argue with that reasoning.
There are not different factions, and really the only benefit is if you want a different race. Theoretically there are different grand companies, but through the main storyline you see them all, and then choose one, you're not really getting a different experience. I understand the idea of comparing equal options, but I just really don't see the need for 8 characters besides messing around, so I consider the basic option, I understand both ways though.
As far as economies, I'm not too worried about that either, even if you were a new player joining an existing server, it just means there's an existing economy like you said. I joined FFXI and there was already a JP player base, I joined WoW on an existing server, I joined Aion and SWToR and others from the start. Nothing in my life changed in any of those situations.
