Instead of making Guild bank expensive, I would like to see it limited to the size of the guild, like 20 members or so. Big guilds would actually need the bank, a small rich guild, not so much.

I mean, guild bank for a rich guild who has 3 members? Doesn't seem right.

So you would only be allowed to have a guild bank if your guild is huge? That doesn't seem very fair. It seems geared to your particular guild actually.
I think that every guild deserves a bank and it does add to pvp. Many people will not want to store their own belongings at their hq but with a bank they will have access to them and will be able to suit up when needed.
Thats what it really comes down to though... if I was a member of someones guild I would not want to leave my belongings for someone else to be able to touch. Then we would hear those stories like "hey man I borrowed your vanq bardiche but I got ganked... sorry" or something along those lines.
