Either way, I don't like the Zone Count of Dragonflight. It is worrying as WoW is a precedent based game and low Zone counts could lead to same Zone counts going forward. Megazones are cool if they are putting the budget and art team at full effort. But, again it could be cost saving measure and a precedent of low/reduction of zone count going forward.
Whether my worries are correct or not remains to be seen, what I do think is that it is silly to ascertain that 4 Zones is normal even if they are Megazones. Yes, we may get two more Major Patch Content Islands too. But, that's up in the air.
I like Megazones, I just hope that it won't mean that we are reducing zone count solely due to Megazones being a concept that now exists in the franchise going forward.
