I think that's what they implied. Pandaren raised the bar with customization, next expac (WoD) everyone else was slowly brought up to par or better. Then they've been doing the same until most of the races currently have a solid level. Now with Drac'thyr they are raising the bar again and in future expacs (hopefully as soon as the next one) we will see broader customization yet again.

I mean in one game it's pretty clear you are a criminal. Hemet is celebrated for what he did to appease some previous century colonialist/anglosaxon archetype about (white) human control of their "destiny" and nature which for some reason the dudebros who made WoW felt was worth appeasing?
