A] I am not on the player's council, I don't know where you got that impression. I am an ordinary player just like you. I don't want some rumour started about me, intentionally or not.
B] I am not going to discuss the potion/salve issue any further. It is a digression and despite the condescending and outright rude replies here, I am not going to comment on the issue except to say that everyone is entitled to express their own opinion, and I stand behind my own despite how much you and the other guy seem bent on 'schooling' me. I am sure the devs will do what they think is best and I trust them to manage their time and resources effectively.
I don't think people necessarily want to annoy. My impression is that, in general, people want to have fun where other people congregate, and sparring is one of the few ways to interact with and entertain others. Like music and dancing. I know for a long time the Snowbourn tavern was a sparring locale and I really enjoyed it. People would hang out there in between raids and spar and watching the spars was a fun way to pass the time while waiting for the next instance to fire up.
I am still searching for that HD sparring arena. Haven't had any luck yet. If anyone finds it post an update here so we can all check it out.
