Limited sprint and squad-leader only spawning for Portal

Been asking for this for ages, but please give options to enable sprint stamina and spawning only on a squad leader when using Portal. These are things that increase strategic play and help characterise Battlefield 2, and in Portal we should be able to play games with Battlefield 2 rules, shouldn't we?

The whole point of Portal is to be able to play any way you can think of, right? So please give us these options so that we can actually do that, and have Battlefield 2-style matches in Portal.

A sprint stamina option would go well with being able to customise the amount of sprint stamina there is, and how long it takes to recharge.
