Decent instance handling options?
 

im currently working on getting anguish up and running and am about 30% done with work on the content. has anyone found any decent options for instance handling that doesn't use a npc that can be exploited as im going for the live like approach?

I'm not really sure what you mean by exploitable, they will work as you write them up to, if you don't check if they're locked out or not it will give it to them again. Looking at Alla, the instance creation/checking if you can do it should be handled in the door clicking events. That is also "exploitable" if you don't check lock outs etc
