How the hell are you supposed to get to a high enough level in say, Hellrunner so that you can actually start dodging stuff?
Perhaps covering behind walls? life is not cheap ;)
Actually, you may think this again when you run out of ammo and you just arrived hell :p

But take all advice with a pinch of salt and try to have your own playing style.
Yup, that's probably the best advice there is. I found that i can win the game with almost any combination of traits, allthough some make life easier for you offcourse. I think the main thing that determines success is your playing style. But never be too rigid about it (like only using coward tactics or never blowing up barrels). Every situation you'll find yourself in can be put to your advantage somehow if you've got the right equipment, tactics setting and a bit of luck :)
