Sony's lack of Dedicated Servers

I'd have to see how much of a difference dedicated servers would make, because honestly, i don't know, but if there is a noticeable and worthwhile difference and it would improve the overall enjoyment of the MP, then dedicated servers really should be used, especially as Uncharted 4 is one of the bigger games coming to PS4 and online requires to be paid for.
