Hello everyone, I've been looking for x1 servers pre-interlude, and after some research I concluded in either la2era (c4) or l2town (c5). Does anyone have any experience to share from these servers? Mostly regarding which one is the most populated, thanks! (Any other such server with high population is always welcome for suggestion - I've also seen l2c3 and l2firebird, but those seem extremely low in pop).
