I remember when 3.0s where kind of rare. Now I see people bitching that they don't have them after playing for like a week. I also see people training the LDoNs with their 3.0s with no respect for other players. I suspect part of the cause of this is people not having had to put in much work to get to that point and in a sense being spoiled.
I dont think the manor in which someone gets their 3.0 has much to do with their training LDON with complete disregard.
