Why does CT have loot lockout?

[Grailer]

I wish they had Loot lock out for Coil as well, Then I might have more luck finding a group when I miss a raid because im on call working that night .

Now with the bad stuff:

Say Mr Dbag tank / {insert a job here } gets an item from first boss , Mr Dbag tank then decides its not worth spending any more time in CT that week and quits .
