Just give it time, while it might suck now the change does make sense since if I"m reading this right a person of low rank gathering could just switch real quick, get their 1 attempt from a rank 5 node and it would count towards the 3 node setup. If you think of it in that context it does feel like an exploit so the change does make sense. Though i do agree that with the odd arrangement of new mobs and even mobs that go as high as lv 99, you would think that they would give us some sneaking abilities. It also hurts that mobs no long have a period of investigation before assaulting us and straight up aggro now.
For Botanist I'm guessing the aggro mobs aren't of the seedkin type or perhaps they are and the Seedkin Eluder isn't potent enough to be at any use if the 10 min recast is right lol. I think something that could work for gatherers though is perhaps a pep cost "sneak ward" basically there could be one for each rank such as the region based one
Activate MP:Perp Cost
LL Eluder I-V:----5-30------:5-30
Grida Eluder I-V:-
Ulda Eluder I-V:--
And then the more defined one like seedkin eluder and such could be
Seedkin Eluder-30 MP, 5 perp cost
Basically you can only have one eluder effect active at a time, you deactivate it by using the spell again and the more defined ones are a lot easier on the MP compared to the region based ones in which you consider it as those gathering classes have knowledge of the reason in which their guild is based on so as they progress they learn how to avoid creatures in said area. But of course the I-V would work like
1-10, 11-20, 21-30, 31-40 and 41-50 mob level, so perhaps at level 50 there would be VI eluder for 51-60 lol. Of course the idea as a whole does need tweaks but I am curious to see how they allow gatherers to have a safer time gathering now that they've added a wide range of high level mobs into the game lol.

You know as a quick fix though I think it wouldn't be to much of a pain if they added a "guardian aspect" for gatherers where you use 1 point to add a "protection ward" to your character so that no mobs will attempt to engage you until they add in the sneaking aspect to the class and it would last til the end of the leve. You would also be able to use both aspects it's just until the fix is made you'd be using 11 GA a leve rather then 10 lol.
