blizz seems to think its funny to close off half of the timeless isle to anyone without the legendary cloak
It is correct that you need the legendary cloak to fight Fire-God Ordos. It's not half of the Timeless Isle. It's one boss -- literally one thing on the isle you can't access without the legendary cloak. You can still get to the area surrounding Ordos using the Albatrosses.
It wasn't designed this way to give us a laugh. The vast majority of the Timeless Isle is open to everyone at level 90, including the four celestials you can fight.
We feel that rewarding those who have invested time into the entire legendary quest chain with access to fight Ordos is justifiable. He's analogous to Oondasta and Galleon in terms of difficulty and loot quality, but isn't just another really rare spawn that can be zerged by everyone in the area, or friends being invited and summoned in.
The original implementations of Galleon and Oondasta were both a little problematic. We wanted to try out a different type of barrier to entry for players who want to fight this boss. And it's fitting that the people who have progressed through the legendary quest chain as it's unfolded, and completed the chain as soon as it was possible to do so (today), get access to him first.
After all, if you haven't been working on the legendary quest chain and/or aren't all that into raiding, it's probably not super important for you to fight this particular raid boss on the first day he's even in the game.
Fortunately you can still complete the legendary quest chain if you want access to the inner-sanctum where Ordos is hanging out (the area you defined as "half of the Timeless Isle"). And it's still perfectly viable to complete the quest chain with all of the updates to it in patch 5.4.
