Sorry but at this point it was hyped from Blizzard and all we got is:
New torghast system re-vamp that is way worse than the originale. Now you haft to spend more time pr. run to clear all mobs, loot all the crap AND! do it on a strict timer WHILE! remembering this bonus crap that is more convoluted than many recently added systems in wow:

Korthia is about the smallest zone added to wow in some time. Smaller than even Mechagon I think. While it has few rares thats rarely up, with again more insane no-life mounts, that even I, cant be bothered to hope to get. On top of that it seems they gated some of the easier mounts like the egg one you need 6 off.
Korthia is also hugely lacking in exploration and things to do. You have some weeklies and 3 quick dailies. That is all. You also only have like 10 treasures to find. Granted these 10 treasures are kinda OK, but mostly simple. Also more currency to farm for not even good upgraded gear. On top of that the BOA tokens starts at Ilvl 200 which is way to low for boosting alts considering the new crafters mark 3 gear is on the AH in few days now.
And then we get the useal raid and 5 man. Which im sure most people enjoy, but its not so much for me.
If it wasn't for flying I was not even the slightest happy about this patch. At least the patch should had arrived 3-4 months earlier, then it would be fair, also just because 8.1 in BFA was also not a big patch.
For now it seems like I will have time to play TBC soon again. Also idiotic that they release TBC and 9.1 at about the same time, on top of having Diablo 2 re-make out soon - Blizzard does not understand their own playerbase tbh.
