This is NOT about flying. Please keep flying out of this, thank you!
Well then. The most open zone we currently have in the game are Suramar and arguably Aszuna. Both of them have their fair share of artificial movement restrictions. Especially aszuna features an abundance of tiny plateus all over the place to limit movement and force people into certain paths. Other zones such as Highmountain, Stormheim and Val'Shara meanwhile are complete and utter mazes to the extreme.
They top anything seen in the game before in how little freedom they give people to find their own paths. They're more reminiscent of Guild War (1) maps with extremly limited movement options than the open world one is used to in WoW. While I like the atmosphere of these zones and think that quite a few of them were beautifully crafted I do not enjoy this change at all.
I always liked WoW because it gave me the option to find my own way, to traverse freely, because it had rolling plans and open accessible maps. One just needs to look at places such as Mulgore, The Valley of the Four Winds, Dragon Blight or Uldum to see what I mean. Yes they had obstacles in them but they weren't outright mazes with people being forced onto narrow paths as their only way of moving forward and in many cases only one right path existing. The longer I play the more cramped, suffocating and wrong these changes feel.
