Account wide bag slots. Make them cost 10x the 'normal' amount for bag slots but let them be account wide. As it is Anet will get no money from people like me for bag slots because they are for one character. Yes, it would be less money for Anet than it would be for just character bag slots (as they are currently), but as most people with 10 or more characters won't ever pay for bag slots at all, they are currently getting Zero dollars from us. So, getting a less than the maximum that it would cost is bad, it's still better than getting nothing.
