Honestly I don't find teleporting to be that big of an issue in members pVp around places like the Grand Exchange and Varrock West Bank. The only reason most people that I fight teleport is because they are out of food. As long as it isn't an organized dm I don't mind this, I didn't get a KO, oh well, most likely they will rematch me. Also, 30's and 40's aren't that uncommon, and I have almost never seen someone who was in a fight teleport from just that. In multi and the wilderness people are going to teleport or log out if they see a bigger team, regardless. There isn't any point in complaining about this, just teleblock them fast, and then wear them down. I can see how the lack of a tb would be an issue in f2p, but you can just go to BH or go deeper in the wilderness.
