Tbh. Graphics isn’t everything. And if they actually wan’t to make the game work as planned, i.e 500vs500 battles, you can’t have 4k models running around and casting 4k spells everywhere.
Look at WoW, sure it has it’s own style, but when it comes to graphics, it’s not that special either… And the servers have problems handling 2-3 full raidgroup in WPvP. And people has mentioned that WoW has actually started to stutter lately because of the limitations of the game client. If you truly want a full MMORPG experience today with lots of people in one area without any sharding , you have to sacrifice something.
