My concerns about a "worldless model" what are yours?

[Jinko]

IF people are not going to use it(like the goobuu) why put it in there in the first place -.-

SE added the original party finder - people didn't use it.
SE added the new search feature - people barely use it.

There is a pattern forming here and I hope that Content finder doesn't end up the same, of course most of the problem with the previous features were they weren't intuitive or demanded a players attention so they went unnoticed.

3rd times the charm .. as they say

I can "Not use it" all I want but if everything in the game is designed around it (instanced) I don't have much choice if I want to play the game do I?

Pretty much, but then you have to re-evaluate whether it is worth playing a game you don't enjoy any longer.

Fact is as others have said content finder is coming, you have to accept that and make a decision.
