On my specialist setup I run HL pro then first kill Assassin.
If I spawn and there is a UAV up then thats great because that's the first point I need to get Assassin. I run stinger on all of my Specialist setups for this sole reason.
From whats been said in this thread though I do understand the reasoning for not using HL, it finally made sense to me when Joe explained it.

And where the hell have you been the past week?
