The only issue I see so far is the party share stuck to screen. I mean, let's face it, if people are going to leech themselves they are going to do it with the auto follow method anyway. This just hurts anyone who wants to split up in Orc Dungeon or something. On another note I feel like it's not a deal breaker for those who disagree with alt leveling via afk'ing but it is a deal breaker for other people who don't have the time and whatnot. Food for thought.
