I've hit 70 on my miner and botanist and gathering collectables for scrips to unlock the legendary nodes however all the nodes are currently "out of reach" so I end up using Toll to unlock losing 300gp.

So what level of gathering is required before the level 65 and 70 nodes are no longer out of reach. I'd then be able to aim for those numbers to make better use of gathering.

I've searched a lot online and the only data out there I could find is for Heavensward so any info appreciated.
