By the way, there's a general misconception that only goblins have too much health, but if you look at the spectator it has twice as much health as it should. In the monster manual it averages like 39 health. So this is a bigger problem than goblins.
Good to know. That makes the issue of HP bloat a bit more worrying.
If it's limited to the occasional monster here or there, that's still probably fine. I'd wager that most DMs have at some point adjusted various monsters' health to be more or less challenging to the party..
But if this continues to escalate through Acts 2 and 3, buffing enemy HP to compensate for increased hit % (importantly, without making corresponding adjustments to ST, AC, etc) then yeahhh that's not the greatest...
