Ok, the T4 one DOES work its just an arse about face way to get it to run.
Once you hit 30 and accept the new mission to goto choas neb and slap the cardies, first goto the Azure neb. Enter an instance and jump straight out again without killing anything. Then goto the choas neb and do the cardy mission and it will complete and you can farm it from there on.
A little wierd and I wonder how the guy found this out but meh, it works!
It's hard to get out immediately, because you usually spawn with 2 BoP already firing on you.
