go into anemos and complete your challenge logs there. you'll get to 22-23 very easily. that should help you get around the first available part of the map. few more nms and you'll get to 25-26. then next week's challenge logs will get you 27-28. and then you're screwed because 4.4 drops and everyone will be doing that for however long it takes them to do that (i'd say a month). then people will trickle back into Pagos.
