Personally, I can see both sides. Could VIP's do with an extra bonus or 2 to entice people? Of course they could. Should it be something as ridiculous as the OP suggested? Not a chance. Some not so game breaking suggestions come to mind. Maybe a permenant 5% xp pot that stacks like the tome of learning. Or, though it would be a little more game breaking, a permenant stacking +1 to loot. Then do not make those boosts available through any other means. Those are going to be relatively minor boosts but, at the same time, gives the ability to get better loots or to grind through TR lives a little faster.
Anything as game breaking as the ability to move BtC items to different characters is always a bad idea. If this idea were implimented then it would be more likely to drive off all of the F2P and premium players rather than bringing them over to VIP. The biggest problem with these threads from what I've seen is that they tend to be VIP players asking for more than anyone should have. The last memorable one was when TR's were given the ability to open hard (2nd life) and elite (3rd life). They thought that they were losing out on so much of a benefit because of that though, to get those accesses, a premium player has to work hard and, for some, can take the better part of a year. Those of you who think this is a good idea, you need to get a brain because you obviously have no concept of what is balancing and not game breaking.
For the record, I am not VIP and never have been. I have spent a total of about $300 between my account and my fiancee's account over the course of 3 years.
