Same! That is what motivated me to try to keep tabs on new oneshots posted to Mangadex. Here is my previous post listing some of the good ones I posted recently. Doing so has caused me to find out that most oneshots are just not very good or are more like art practice than anything else. A recent example is Battle. It is impressive art, but not really a story that I found interesting enough to post. A lot of oneshots don't even good art going for them, let alone a good story (example).
