Why is there a staggered release only for the first tier of Savage and the Ultimates?

Then why are the Ultimates released at a later date? You can't say 5.2 is when they decide everyone has had enough time to catch up because the 5.3 Ultimate will be released a few weeks later.

Ultimates are released later because you need to clear the Savage-Tier first just to be able to enter it - and you need also to gear up with BiS for it, which means you need not only clear it, but also get all your equipment which can take a while.

I don't know what you are talking about 5.2 or 5.3 though. There is no so called "5.3 Ultimate" planned at the moment. We don't know how many Ultimate-Content we will get this expension and even if there will be more we don't know when. Maybe the one now will be the only one we get.
