The game chose a different target difficulty than you expect - that doesn't mean the game is bad, it just means you have to choose; change your expectation, or run the game in a way that it meets your expectation.Yeah, in 5E, the only proper name for four trolls vs a level 10 party should be "a complete waste of time".
Okay, let me rephrase:The game chose a different target difficulty than you expect - that doesn't mean the game is bad, it just means you have to choose; change your expectation, or run the game in a way that it meets your expectation.
Constantly flinging mud at the game instead of saying what is actually true (in this case, the phrasing would be something like "I don't like encounters to be as easy as the 5th edition guidelines") isn't really benefiting any points you might otherwise make.
Still, calling any encounter easier than what 5e calls "deadly" "unexciting filler" isn't universally accurate.Okay, let me rephrase:
When you convert, drop most encounters that aren't deadly or above, and upscale the rest; unless you want strings of unexciting filler combat that mainly wastes time.
