Of course it doesn't include DST. Gruul isn't T5 content.
So, a handful of items. At most. This isn't really a point. This is an opinion. What you said in your previous post about this isn't really correct, either. Ideally, items indeed aren't released on the marketplace until the next tier is available (and part of it is), but whether an item is on the marketplace depends on how much the boss and the items in question are being farmed. It's very common that what is on the marketplace isn't ideal for some people. Many people have varying opinions of what should and should not be on the marketplace.
You are aware that after all of the raid content is available on the realm for a little while, 100% of items available from them will be on the marketplace, yes?
You really should be providing quotes when saying such things. And if someone did say explicitly that, then it needs to be ammended. But in any case, we are allowed to change our minds. That's not to say that a modicum of fairness won't be maintained, because it will. However, overstating and misquoting things will cause needless arguments and upset people.
I agree with this. Marketplace releases may interfere (as being bad, or as being help, view points may vary) with people regardless, because not everyone is doing the absolute latest content. But for those that are, these item releases are hardly relevant. For those that aren't, this would still be the case if Black Temple was open or not.
