I agree that missing TBN procs feels awful, but I love that aspect of it. There's not much to do while tanking, and timing TBN is one of the few actually-difficult things we have. However, the actual uptime on TBN is stupid. The horrendous delay and short duration on its cast makes it ridiculously hard to time it sometimes, especially when server lag is so volatile right now. I don't understand why the effect isn't immediate when almost every other skill feels relatively much more snappy.
