What do you think about item pop NM's?

Actually if you think about it, Instances are more Taxing as the require the Server to load multiple version of the same zone(this is why there is an total number of instance cap). The only reason they are better than the current system server side is because the zones are so big and have to be ready to load in at all times. When they transition to smaller zones it will be significantly less taxing to load one dungeon for everyone than to load a whole dungeon for each person. Instances only appear less taxing on the user end because it is the number of characters, not the number of instances, that creates client side lag.

Actually there are things called instance servers and your character is easily loaded into them.
