I think that consistency is a huge part with any of these rules. I played basketball in school and college and travelling was one of the rules that had different applications with different refs. It can be frustrating that a player can do steps and jumps in one game which another ref might call.

I tend to get very frustrated with the technical fouls as they feel unnecessary even though they are part of the game. I only see a foul when a player get taken out of the game and everything else is play on.... but the rules are there and they make the games what they are.
