I've been following the progress of the project for a while now, being very interested in it, mainly because of its progressive chronicles idea to maintain activity.
But why x7?
It means server will be LOW rate, and a bunch of people won't join just because is veeery long until you reach the fun, there is no actual fun on leveling your character or being low level for THAT long. My point is that at this time Lineage is not know for being the most fun game on lower levels, so people just want to get to 76 as soon as posible to have a chance on pvps.
Not to mention that 10-25 years old generations doesn't play Lineage, it's an old game, and people older than that have family, work, business to take care, etc.. it means not enough time to play a low rate server, if you don't compensate the offline time I estimate low pouplation, remember Lineage is a farming game, more farm = more items = more chances on PvP, no good items = no chance, of course hability plays a role but S grade VS B grade is not good (except for daggers)
Aditional question, are dates for open beta defined yet?
