1. Not a fan. That might change once I get good at it but even then I would probably prefer nomod. I don't care about score and the pp increase is thankfully small enough for me to feel like I don't need to play it.
2. Hidden doesn't make a difference to a player's respectability, except for two cases:
- If you set some great scores on hard reading/tech maps with hidden that would be respectable as hidden makes those maps in particular much harder.
- If you play hidden on farm maps and get low accuracy (like your profile currently is), it lowers your respectability because it shows you are chasing pp instead of actually trying to improve, get good accuracy and set good plays.
3. Difficult, but not very. I imagine with enough practice it would be the same difficulty as nomod (except reading/tech maps would still be a lot harder with hidden than nomod of course).
4. There isn't one, some people like it and some people don't.
