As far as I know, there is no limit to the number of ancient logs you can harvest in a day (as there is for, say, blooming passiflora), so I don’t get it.
There is definitely a daily maximum amount of times you can harvest all T6 resources on a per map per character basis, just like passiflora and other resources in Southsun. There is a limit on mithril/elder wood in Southsun. There may be a much higher limit on all resources as demonstrated by bloodstones in the new zone, but T6 and Southsun are the most noticeable. After you’ve reached the cap, all nodes of that type will appear as already harvested and not show on your minimap.
Rich nodes in the same map also have a cap, but seem to count towards a different value than the standard nodes, again most easily seen by harvesting mithril in Southsun.
Yeah I would also have to disagree with this assessment. The only place I’ve ever noticed a limit on Rich nodes is Silverwastes, and that limit is immediately noticeable. You can harvest from one of the Rich Mithril Veins for the full 10 strikes, and then when you find another Rich Mithril Vein you will only get 3 strikes on it before it shows as depleted. SW is the only place I have ever seen this behavior.
I can’t speak to Southsun as I don’t regularly harvest blooming passiflora, but “standard” T6 on other high level maps are always available for me to harvest. I run nodes on a regular basis (it’s one of the primary things I do in this game, laugh if you like!), and my route is typically Brisban > Maelstrom > Blazeridge > Harathi > Malchor (and sometimes Frostgorge). Brisban, for example, usually has three Rich Iron Veins and a Rich Silver Vein. You can harvest all four of these rich veins every day, provided you are able to locate the two “traveling” veins easily. The same case can be said for most of the other maps—there is no limit to the number of strikes you get on these nodes, but occasionally you may be hard pressed to locate all of the rich veins in an area as sometimes they “spawn” in hard to reach areas or places you might not usually check.
That said, rich veins refresh once daily, and T6 nodes also only refresh once daily, at reset, much like vegetable farms (or flax farms). Also it is worth mentioning that if you harvest from these veins/farms/T6 too close to reset (~10-15min before reset time), you may have to wait a fairly significant period of time before they will refresh, and in some cases I have seen them not refresh at all until the following day. Always hit your 24hr timed nodes well before reset (I usually try to hit them 2-3 hours before, and run regular nodes until reset) to ensure they refresh for you to harvest again.
Running nodes might not be the most exciting way to play GW2, but it certainly is profitable. If you don’t want to run multiple maps (I do, simply because it breaks up the monotony), you can easily run the node-rich areas of Brisban, Maelstrom, and Malchor’s, and by the time you finish with Malchor’s the standard nodes will have respawned for you to harvest again. Lather, rinse, repeat.
If you are having a problem with one or two T6 nodes not refreshing for you, it may be wise to start keeping a log of when you last harvested those nodes and check back periodically after reset each day to see if they’ve refreshed. If you harvested an Ancient node 5 minutes before reset, it very likely will not refresh until the following day’s reset (eg: in 5 minutes plus 24 hours). If you’ve gone a full 48 hours with the Ancient node still not refreshing, submit a support ticket to see if something else is afoot.
