Like I mentioned in the post you quoted, I didn’t give values for the examples because I thought those exact values should be the way it is. I was just trying to get the main point across. Also I know preparing say a level ~60 account does not take minutes on Classic so I doubt it would be abused all that often. As for what I mentioned about the playtime, once again I did not give values for the purpose of creating an exact amount of playtime required. It was to get the point across.
Regardless of any content added to the game people are always going to find a way to abuse it. That is why we have staff members to look over the tweaks and to make sure if anyone is abusing them to put a stop to it or make changes if necessary.
^ this is exactly what i talked about, there is always a way to abuse every pvp related update. That should not be used as an excuse not to move foward in an environment that is currently dead.
