I do not think this needs a rule at all. In the old days stuff like this happened. You dealt with it without crying. If you wanna wait until tick 1000 to start playing actively, well you will need to deal with the fact that the relics can go out to sea, you CANNOT reach them, and you WILL lose. Thats just that. Dont let it get to that point and you are fine. Crying about "WE NEED A RULE" after it affects you is total crap. The idea of the game is that relics CAN go anywhere on the map, and you CAN keep all 10 safe in the pacific ocean, and if you do, GG WP.
I will reference Earth 1, era 10 here. Rania and Pantera if you guys check the forums and remember the era please coroberate. From what I recall Trajic threw a hissy fit that Rania did not invite him to her team. made a team in NA, took hawaii, and while Rania was busy fighting other teams he got 1 relic, and flew it out as far as he could in the pacific. Rania had the era secured by tick 1000, but it lasted almost to 2300. from 1000 to 1700 rania killed teams that she would normally have left alive just in case so they did not stab her. The rest of the 600 ticks she had to fly one of HER RELICS from New Zealand all the way to the west pacific to take the ONLY relic trajic had, which had about 200 squads on it if I recall correctly. During that era not once did Rania (master of whining and complaining keep in mind!) EVER ask for a rule where relics are not to be kept in the pacific. This is how it should be played. Now the fact that iceman did not HAVE a relic to fly out was his fault. Play the era sooner, and it wont be an issue.
