IMHO tower sitting in and of itself is harmless. The problem as far as I am concerned is ENY. It needs to be restricted and reduced to accommodate for the lower #'s. Dale is open to ideas but at the end of the day it works most of the time hence why it remains.
For some people this game is more than a game. It's a part of their routine day in and day out. If your not one those folks then it's really difficult to get someone to understand why someone might stay in the game even though they are not playing.
It's another one of those is what it is in today's AH. Just don't let an issue like this fester in your mind for extended periods of time like I have. It made me bitter and effected my ability to enjoy the game for what it is. Even threw a few tantrums over it and all I accomplished was looking like an idiot
