much more likely to give you what you want

I'm not sure "improve the old roll system" is the right way to phrase it, at least in the context that you have any expectation that the bonus roll should be much more likely to give you what you want,wow gold if not at least know not to give you what you already have.

Using a bonus roll is effectively no different than if you were to be able to loot that boss twice in one week. Each bonus roll provides the same chances of getting gear from the exact same loot tables as a normal loot roll -- nothing more, nothing less.

So it's an improvement in that you can earn an extra shot at a boss's loot table in one week. But it's not intended to be a system that ensures you never get what you don't need. The random loot system can only be so convenient before it becomes too efficient. We believe chance should dictate whether or not you get something at all and, if you do, whether or not you need still need that item. That philosophy -- specific to boss drops -- hasn't changed much over the years, so it stands to reason that even a bonus roll would follow the same structure.

But with that said, we're exploring ways to make the bonus roll feel like more of a random bonus, without just making it extremely efficient for gaining character power. We understand how it feels to spend the charms and rarely see anything other than gold or items you don't need. So, for example, we could maybe add pets and mounts that would have a low chance of dropping exclusively on a bonus roll.
