Answear to ur question is : yes.
Even more, its very easy if u have basic knowledge about rolling mechanics.
It was easier when there was more servers in region, but very easy those days too.
Without any macros, hack, cloning, or rules breaking.
Many players and fleets on EU servers had required "know how".
And my questions to U:
Please explain me how should look macro rolling same sailors ?
:D :D :D
a bonus: how long u play this game ?
Becouse if its ok with my memory, longtime ago some players from NA also knew how to do it.
