I have made a video showcasing this behaviour. Seems to confirm that when approaching from the front, stealth is effectively useless because the mob will aggro you at the usual aggro range for your relative levels. The mob does not face your direction before attacking you and unstealthing you to warn you, the mob will attack with no warning. As I said, If this is how it was intended to work in Vanilla and it was changed in a later patch, I cannot find a note documenting it. I might test on Kronos as a cross-reference next. https://www.youtube.com/watch?v=PXmUGvLD_5o

I have noticed questionable stealth detection too. Stealth from the front appears to be detected by equivalent level mobs at their normal aggro radius, rendering it completely useless unless used from behind. You say this is Blizzlike for Vanilla Fisher but try as I might I can't actually find any patch note where they significantly rework the mechanics of subtlety and detection (the two invisible values all players and mobs have that determine detection). I've only found a few notes about fixing a few bugs with damage breaking stealth and items that grant increased detection. I will do in-game testing on this on my druid when I can log in later today and post back, approaching a stationary mob from the front and back, stealthed and unstealthed.
