Early on in my GW2 days, I remember actually escorting Mona with a group of other players. Without even thinking about it, I was using my mount to bust up the attacking Centaurs and was killing most of them myself. Another player called me out on hogging all the kills and not letting other players get any. My initial reaction was very salty. As I thought about it though, I realized that player was right. It is a matter of common courtesy. Ever since then, I've been mindful of other players on the lower level core maps. So even if someone's initial reaction is testy, you may have a positive, long term effect, without ever even knowing it.That is great that you made a change. I swapped to using my jackel in low levels zones and giving newbies the hp barrier, instead of the raptor tail swipe :)
