Another thought.
Whilst war is indeed a part of the game, what we often saw happen was clans who would simply bulldoze a tag set in and set out, with no diplomacy, rhyme or reason, simply because they "didn't like" that tag. That doesn't keep players either. No one wants to play and get killed every single set because a group of other clans (and it was regularly coalitions) think its funny to do so.

Now, I'm not talking recent history, but going back way back, just to be clear.
