I dare to believe that is their point ...
Larian wanted to see if players are able to deal with small parties of lower levels but good positioning (mostly Blighted Village) ... big groups of average enemies (imo Gnoll encounter) ... average groups of average enemies with reinforcements (hooked horrors, drow/spectator, Duergars, potentialy Hag) ... Big ass monsters (minotaurs, Bulette) ... and higher level average group (Gith patrol).
Pretty sure level 5 player race characters don't have at least 61 health, usually around 90-something. And multi-attacks. Even if the player's party was level 6 or 7, I can see this group of level 5s mauling them quite handily. The idea of a 'mirror match' where it's a group as strong as you is a fun idea, this just feels incredibly cheaty to the point it's actually boring; it's not about a 'good fight' anymore.
