Guys if the pvp world was an actual pvp world then pvp'ers won't move to the green worlds, depending on how JH is implemented they won't go to a green world except in the case where they need gold coins, I personally wouldn't move to a green world because it would be a waste of my time.
I complain about JH not being on during the day, what could possibly make me want to be a on a server where it never happens? The worst you will get is if they make JH long and throughout the day, the people who work all day and come home to play some JH in the evening will probably move some characters over to the green worlds so they can avoid an evening of fighting.
The idea that guilds will move en-mass to green worlds to escape pvp who actually want pvp is a fallacy, just in the same way guilds on Eve don't move en-mass from null sec to high sec to start PvE'ing
The truth of the problem here is there is no barrier between full pve worlds like Epeland and half pvp worlds like Skjutland, the Eve devs atleast new that logically you didn't want null and high sec bordering each other and that you need a low sec in the middle to ease the transition between a full pvp and non pvp environment.
Which is why we need the same in Life is Feudal, so for example the line of transition between worlds should be something like Epeland (High Sec) > Skjutland (Low Sec) > Avalon (Null Sec) with Epeland having no JH, Skjutland having similar system to Avalon now, and Avalon having a 24/7 JH type system.
You can't travel from Avalon to Epeland, Skjutland produces gold coins but they can't produce slaves (they can produce Barmosag tho), and when the devs feel they need to add a respective world they shift it into place with the other servers, and instead of just Green and Red you would have Green > Yellow > Red.
More options for everyone and the green servers don't have to worry about being overrun by a recently defeated enemy who is being driven out of the red servers, and is recuperating a loss.
You could even apply more protection on the green server, such as the inability to hit anyone unless they agree to a duel, IB's could do no damage so you could have regular IB's with no consequences, and when sieges come you could have regular sieges where nothing gets destroyed or taken over.
A true PvE world.
This would leave for more open on the yellow and red worlds where people who work or can only play in the evening can live on the yellow locations, and then no life's like myself can juke it out on the red worlds all day fighting.
Everyone is happy
