Common Courtesy with End-game Raids/Dungeons

[Gandora]

I guess the JP community uses DF for winning and PF for learning. I don't like this approach because there's less challenge, less mixing of vets and noobs. It optimizes farming and isolates noobs. It's ok that different places have different gaming values, but I don't want this approach in NA community.

Ohh because the current approach doesn't isolate the beginners?
