It's not a switch they can just flip on, it would take a LOT of work for the devs to prepare it.

Also, they have said they don't want Luclin on p99, so we won't see it here unless they suddenly decide that they actually like Luclin after all. (not going to happen)

Luclin is kinda terrible tho

Custom content would be great for blue at some point <3

I posted something similar recently, but custom content I'd like to see are:

Whats behind the EK waterfall?

Betwix Oasis and South Karana.

Travel zone between Lavastorm and Everfrost.

yeah! there's some lore about Miragul could be fleshed out

This is about as classic as it gets.

The people who run P99 changed the game that split the player base and the majority left for WoW.

Will the last person leaving p99, please turn out the lights?

This.

(but not Lewshleen)

Pixel lust

So green server was a mistake then?

Nope, rooted dragons is what set Littul off. His guild had just got to the point where they could zone pull them and be competitive, others got to enjoy the gravy train before the change.
