The only thing that prevent me for mapping (because I'm no professional)is mainly:
1. Manual BPM setting (so tedious, is there any alternative I wonder...)
2. Abbreviation and other things that I didn't understand(SV, 1/2, 1/3 I don't understand)
3. There's so many things to do, but can't really tell the actual phase of it (like step-by-step or something)
4. Unwritten rule about certain things (maintaining the flow, set a fitting AR, CS, and OD for each difficulty [FAQ is not related], and other)
Is there anything that can help me solve this problem, then I'll map right away
The first one is something you can solve, by using a bpm analyzer. It's sometimes not accurate, but gets a good bpm pretty often, from what I hear.
The second one I think can't be solved. For any task, words people will use a lot will become abbreviated, it's just life. But normally you can ask the person about it and they'll tell you. (Oh, and just for completeness: SV = slider velocity, how fast the slider goes. 1/2 and 1/3 refer to a number of beats, e.g. half a beat, one-third of a beat, etc.)
For the most part I agree with the rest of your post. Mapping if you're new is like swimming for the first time and being pushed off a 12-foot diving board. I know of a couple people who are putting in effort to make the mapping community a better place for new mappers, and others who have expressed interest in creating tutorial series to help people learn technique. I'm far from experienced, but if I had any advice to give, it would be focusing on creating something that's fun for you, instead of basing your opinion on your work on what other people think about it.
