Count me in as another vote for more character slots per server.
We've heard from customers who say more than eight characters per server isn't necessary. Strictly speaking, this is a game, and it isn't necessary for any of us to be here playing at all. What all the "eight per server is fine" posts I've seen are saying is "eight slots is enough for my preferred playstyle". And that's great for BioWare to get that feedback from customers.
We've also heard from customers who want more than eight slots per server, with their reasons (like seeing what difference light/dark side makes on a given base class storyline, or wanting at least one character of each race).
From a player perspective, I haven't seen any argument against allowing more characters per server. Some players aren't interested in any more, but I haven't seen an argument about how more characters per server is a detriment to these players. Those of us who want more characters have outlined how not having the slots is a detriment.
And the Legacy system just made it worse.
I'm a newer player. I have a couple Imperial characters and a couple Republic characters on a single server. I had just decided that I was going to reroll my Republic characters to another server (as I'd like the option of at least eight slots per faction) when the news about the Legacy system hit. Now we have a problem. The cooler the Legacy system is, the more pressure BioWare is putting on players to concentrate all their characters on one server. (And with cross-faction mailing coming, I'd also prefer not to need to duplicate crafting professions as I would with two servers, but not on just one server now).
What I'm asking for from BioWare is this: make a decision about whether or not you'll expand characters per server, and make it very soon. Then announce it. Right now, I find I'm "in limbo" on a couple of my characters--I don't want to reroll them elsewhere yet if there's the possibility I can keep my whole "family" on one server, but I also don't want to play and invest more time in them in case I do need to give them up later. Lay me out a road map. I love this game so far, and it's killing me not playing my Jedi because I don't know whether you're taking the request for more characters per server seriously. If you're not, please, don't string us along. Make a decision and tell us what it is.
