I'm playing a level 10 fighter, a pretty vanilla 2 handed build. My group has recently had some trouble with a ninja, and I feel that for both reasons of revenge, and to prevent future trouble, I'd like to focus more on fighting rogues and ninjas. So far, my main obstacle seems to be losing the initiative and taking a ton of sneak attack damage in round 1. Can anyone recommend some feats or equipment to level the playing field?
