So being a Rank 50 BTN it's easy to say that I enjoy gathering quite a bit but there are a few things that really do annoy me when it comes to gathering and many of them are easily fixed and logical to boot so I thought I would talk about them a bit here.
One of the biggest is getting rid of +1 and +2 when gathering. SE did this for combat and it helped with cutting down the clutter quite a bit. However when going out to gather we still end up with flooded inventory as we get 4(NQ +1 +2 +3) different types a branch for each kind of tree as well as 4 logs and 4 feather and 4 random things like chestnuts or what have you. This clogs inventory up VERY quickly and when combat was fixed to avoid this issue gathering should as well as you gain items in gathering much quicker then you do via combat(for the most part). It's quite annoying to go out harvesting for awhile only to quickly get a clogged up inventory and then have to choose what to toss and what to keep. We harvesters are often quite a distance from town so we need as much help in inventory management as we can get.
Another issue is the sweet spot system. The idea behind it is great. Being able to find and target a sweet spot and then get the item you are looking for easier. Awesome idea. Except it doesn't really work. I can't count the amount of times I will be going after a item targeting the sweet spot and walk away from a tree after 8 attempts not once getting the item I was aiming for. That's far to random to be considered a sweet spot. If I aim for the Walnut Log sweet spot I should be getting the Walnut Log 50% or more of the time but quite often I will aim for that spot and not once get a Walnut Log after 8 attempts(Walnut Log being just a example as this is the case for nearly any item I am aiming for). I think the rate at which the sweet spot yield it's item should be increased a bit so as not to seem to random. I know it shouldn't be 100% but it also should never make you walk away from a attempt with none of the item you were aiming for if you were doing so successfully.
Third on the list is making gathering possible everywhere. Considering that Logging, Mining and Fishing are real classes and not just side skills they should be useful EVERYWHERE. I don't want to be running through a area and use arbor call to be told there are no trees in this area. I can clearly see trees around me(and there is always water and rock around as well) so I should be able to do something in these areas. I'm aware that there are not a ton of grades yet but they should still have more harvesting areas.(after all they can change or modify what areas yield what later. Which as a matter of fact they have already done to several areas)
Another minor gripe I have is aggro. Gatherers should have some kind of ability to help with aggro when getting to or around trees.(and I'm talking all aggro not the certain kinds of mobs thing you can get which are useless in my opinion) Think something like Camouflage like ranger got in FFXI or Hide that Thief got. Also make it so that once you start a gathering attempt you can't get aggro. SE has done a good job for the most part in pulling mobs away from gathering areas but there are still a few areas that are a problem and it would be nice to not have to worry about aggro once you are already on the tree. But again this is a minor gripe compared to the other issues mentioned here.
