I find it fascinating that you had this happen but now fail to provide the specifics of what you changed such that another person might take advantage of it and thus create an act of kindness. Hope this just isn't some kind of mind trick to get people to tell you how to make specific builds.
No not at all. I am just back after a year away, so the event I was recalling was well over a year ago. The specific advice I do not recall, but the event is still memorable to me. Just the time and effort this person took to help me out stayed with me.
Any Sniper advice I give now would be out of date after all the patches and updates since I last played. I hope you understand this. Cheers!
