There certainly arent people beating down our doors to use our whopping lvl 3 alchemy skills but there are people who do need the help and go to lower level alchemists who need the experience instead of lvl 10s who dont.
Also you might feel less depressed about it if you didn't bump your thread so much. This isn't something that happens over night. I've not even gone past the second page of my shop yet and I have stuck comfortably at/near the top of the subforum just by checking on my thread occasionally rather than bumping costantly :3
