1. Make ENY twice as punishing than it is now.
2. Enable zone ENY; allow it to also affect global ENY as well. For example, if you log on and your ENY is 10 but you go fight a horde it could potentially eliminate your ENY penalties.
3. Entertain solutions to the large map/few player conundrum. (I don't have a fix to suggest)
4. Change the 12 hour side switch rule to 2-4 hours.
