So for flying I need all quests in every zone and a complete Suramar questline plus exalted? That is IT, I am out.

I am still confused why people call Legion the "best xpac ever" and Pandaria is getting so much flak because I loved Pandaria more.

Pandaria did everything right for me.
Questing on foot: With the great landscapes I enjoyed this the most).
Max level with instant flying (I hate the prereqs in Legion and WoD)
Not trying to disguise daily quests (I mean come on, at least Pandaria daily quests were concise in one area, also I don't care what I slay 8 of for my loot)
Well done cooking (instead of a cooking NPC called Burn It McFlameface aka Nomi)
A smidge of player housing with the farm which is entirely optional instead of required player bases with the order halls.
A starter raid and two more advanced raids on launch (though I cannot say anything for Legion raiding since I feel being in LFR once is not a fair assessment)

The only thing Legion did better was the weapons system and the mythic dungeons.
