I noticed that after the initial fight at the entrance of the Grove astarion suggests to immediately leave because most likely more goblins will come. Issue with this is if you do so you will not know about the auntie Ethel option, nor would you know about priestess gut. Do you even know halsin is a healer at that point? And finally if you do follow astarion advice why would you then go into a full camp of goblins considering you're trying to avoid goblins in the first place. And then what, the only options left are the gith and Raphael which you can't do in ea. You have a map full of places that you cannot explore cause goblins!
you learn about Halsins healing inside the grove from multipule people, you may later learn about it from some other source depending on what you do, where you go. The same is true for Priestess Gut, most of what you learn is centered within the druids Grove well it's the easiest place to pick up info. Other paths you take may well lead you to some of the knowledge found in the grove, but not all of it. As for avoiding goblins that also depends on where you go. I believe not 100% certain there is a path around the goblins, but again your looking for a healer. If you chose to not go into the grove that limits you to the cambion (if/when he shows up) and the Creche right at that point. yet you also don't learn things that La'eazel wants you to at that point.
