In comparrison to the people who enjoy both styles of sniping, those who do complain are in the minority and tend to be in the higher skill bracket and, as J.D. put it, are more used to a certain style. There used to be so many HS-only servers, and now most have disappeared and Snipezilla took up the reputation as the sniper's hub (at least for America and several parts of Europe).
Either way, they have Sanctuary now, so they don't have to stand around and soap on the server as they used to do^^
Also, I still don't understand the Classic. Haven't gotten a chance to try it =p
When you zoom in, you can see in third person mode. You can't get a headshot until fully charged.
