Just use takedowns when you're at 1 so you aren't "wasting" any. Using takedowns on every enemy would be insanely tedious though.
Just started my 3rd playthrough yesterday, I'm amazed that I'm not sick of this game yet. This time I'm just blasting everything in sight and it's extremely fun. Revolver + shotgun/MP and I'll probably grab a crossbow for long range.
Oh man the revolver is fantastic at medium distances and closer. That was my main weapon of choice. Then I got the plasma rifle and that thing is just plain silly. The turrets at the end didn't stand a chance.
