Sounds more like the actual content is too easy vs. the content finder actually being detrimental. If you can do most content in a pickup group there would be no point to tight-knit linkshells regardless.

I don't have a problem with finding groups easily to do one group dungeons, who really wants to wait 4 hours for a group like you had to sometimes in 11? But if you have raids that you can beat with a pickup that's more of a problem with the game itself than the content finder.
