Hey kraken,
where do you take your information from? Im refering to this thread: http://forum.game-labs.net/index.php?/topic/14816-update-on-the-port-battle-set-up/
If you read this carefully, according to the dev there is no limit to how many hostility zones a nation can create. So one nation can create 10 Hostility zones and block all other nations out. (Talk about defensive tag ;D) And if you continue reading carefully u will stumble upon this
So in contrary what you are writing I just need to sink enough NPC fleets to triger hostility. Which is as i stated before much easier if u have double the population than other nations.
Not that a underpop server is really a reference, but basically u agree with me even tho u say u disagree. According to you only the most aggressive and populous nation will be able to take 3 Ports. So what about the low pop nations? Yes they spread more slowly like I said.
The potential for abuse is there if u deny it or not, hope the admin will implement some protection mechanism there.
P.S. I'm not saying hostility system is bad, but the global 10/day limit is. Make it 3/day/Nation i.e. and it will be much better.
