How badly will shit be camped?

[Noselacri]

So everyone knows that a portion of the playerbase is extremely hardcore and will camp shit religiously, but how bad will it really be? Should one believe the horror stories of "manastone will be camped 100% of the time from release until removal"? What about other things like regular xp camps, will they be perpetually occupied with a list of 20 people in line? It's kinda hard to get an idea of these things because blue was way smaller when it launched.

Vanity items like guise, can you ever expect to get one if you're not part of some poopsocking crew?

Will regular people be able to get into high-value camps like FBSS or GEBs?

Will solo classes actually be able to find good spots to solo or will all worthwhile content be occupied?

Can you expect to go to a dungeon and /yell LFG and actually find a group in reasonable time or will it be hours of waiting for a spot?
