Let's face the facts, you want noobs to do delve. Not enough of them to Noob it up together.

Waiting all day to PUG during primetime? Horrible. Can't play during primetime? No Delve then.

FACT: Everyone who is doing Delve PUGs knows everyone else who are doing Delve PUGs..

Time for a merge..!

Issues:
Can't get people to do Salvage, so bad people are paying others to meet entrance requirement.
Can't even find members to do Meebles, most do not care anymore because its such a hit or miss.
No one reives. Bivs do not consistantly exist past frontier!
No one WOE. Implement WS coin unlock already.

FIX IT suggestion:
You should Gather together the JP and give them the option of an existing high populated JP server, unite them all and give them the ability to do things w/o the issue of underpopulated language restricted gameplay.

You should merge the lower end servers with the higher end ones and balance out the medium population.
