Ragers, at least the ones worth killing with the rarer gear, will never thirst outside of walking distance of the Village.
If you go at them one versus one, especially if you can't lag more than two rounds, you are very unlikely to manipulate the field enough to run them out of MV's even with hamstring or fatigue. Without being an airform, having summon, crippling strike or an orc using hack leg, (4 rounds), catching up to them is unlikely and strictly a matter of connection.
If 'prep moar noob' is the answer, then 'gang and full sac till they delete' is an easier answer.
DB blows. Alot. And I refuse to take 'don't fight them' as the answer for lazy prepping.
I refuse to take any answer that increases my timesink. It's better to increase theirs till they think the given character isn't worth it. And the beauty of CF is that isn't against the rules, and when you get bored doing that yourself you can just delete and re-roll.
