When Strongholds came into play I was stoked. You could use them as a "safe" haven and meeting point for your clan. They cost a lot of coins to have,and with the rent so high,and every character can go into them It is not what I had in mind.
I think It should be made that only clan members can go into peace room(Inn)... but if a flagged person is in there then it is a regular room....no peace...no clan tag only....The stronghold guards are a nice addition, However, employing guards would add to the cost of rent, as well as a substantial fee to begin their services... and there would have to be a limit set on the guards a small/medium/large clan could employ.
To prevent the "tunnel" that was mentioned earlier:
An in has to be in its own room with only one exit. Once the Inn is established there can be no more building onto the Stronghold.
