I'm new to Dagorhir (last week was my first event, a local chapter practice). . . . He was also a talented fighter and whenever we'd meet up on the battlefield, he'd win 7/10 times.
Those two sentences aren't meshing well for me. Either you're not new, or he's not talented.
As to dealing with people "not taking your hits":
I have come to the conclusion that there are no rhino hiders, or people that don't want to take their hits on the field; there are only people who want to be hit harder . . .
This, really. The moment you start assuming that if he didn't take a hit, your shot wasn't good enough is the moment combat drama flies out of the game. I mean, there are
rhinohiders. There are
people who have hands that come up to their elbows and legs that go-go-gadget extend up to their armpits whenever they get hit where normal people have hips. Oh, well. Just do better.
If you really
think there's a problem, talk to a herald. If there's no herald, talk to someone who can talk to the guy from whom he'll take it seriously. A lot of guys with bad reps would be horrified to know that people have an issue with their hit-taking, and if someone would just tell them, they'd either explain the misconception or work to improve.
And maybe you were hitting light. Breaking a sword isn't necessarily indicative of your stroke.
