When I asked Se to make this game more grindcore.
I don't mean make it a hardcore fest...

When I asked se to make this game less Time consuming...
I don't mean make it like a no time at all thing...

... lol I can't keep it up. Anyway-

Hardcores and casuals can coexist. The fact is hardcores are a minority. Not all content can be built for hardcore. I don't think Hamlet defense (which is what you're really complaining about) is going to be an endgame activity in the long term. Thus, I wouldnt really change it much. Eventually, you will be moving on to a new endgame content and you won't care about Hamlet anymore, it will become a more casual thing.

The fact is, for a more casual player who hasn't spammed it enough to get it perfect yet, hamlet defense can actually be kind of challenging. My first few runs were with pickup groups and we all got humiliated. Then I went with a more planned out team with a specific goal in mind and it went smooth as butter. Difficulty is subjective.
edit-
yes, i got an idea:
don't do a thread with hardcore vs casual in title, because they get a flame-hole. Seriusly.
Pretty much this... don't throw around words like hardcore and casual when that's not really the issue of the thread.
