The important thing is to provide a quality approach.

Showing all mobs then eliminating non-clients is just a bad approach. Why not show all clients and eliminate those without a mob first?

Using a switch, when you only have one value is a redundancy which needlessly complicates the concept. Same with lists that store 1 or 0 values max - what is the point? That is like saying you're going to create a datum that will only have one property defined with no functions. You don't hit a screw with a hammer or you'll see issues down the road if you don't see them right away.

YEY I'm glad that i could help :D
