You're late to the party Ethical. His original post was highly offensive and featured insults in both english and korean aimed at Zwiebelchen personally. This was later edited out so you may feel like you have some moral high ground here, but you don't.
Nobody owes anybody a direct apology on the internet. If you want to get offended by something which isn't actually criminal, that's your own problem.
Again, you missed the 2 paragraphs worth of flame and tears about low drop rates. I personally don't mind it since, legendaries are supposed to require some effort and time to get. If everyone can easily and quickly get a legendary, they wouldn't be legendary anymore. Also, even though Koreans can play and grind much harder than us, we aren't getting beaten by them at all. Don't forget that a lot of us have been following this map for 7 years and jump on any new content as soon as it's released. This is probably one of the very few RPG maps where the english community is always ahead (in terms of legit players anyway).
Conclusion: If you find a game boring and tiring to play, simply refrain from playing it. There are plenty of alternative options out there that will be better suited to your tastes.
