Another follow-up for the new tank

Blizzard's September 17 hotfix reduces D.Mon's armor by 50 in both formats: 325 to 275 in 5v5 and 300 to 250 in 6v6. The entry also adjusts her weapon and perk tuning. Separately, Mercy's Stadium bug is fixed and she is re-enabled across Stadium queues.

Mode labels remain important. A reader checking a 6v6 armor value should not use the 5v5 total simply because both appear in the same patch entry. Similarly, Mercy returning to Stadium is a queue-availability fix, not a new standard-mode support rework.

The live comparison moves forward

This update follows September 8's wider balance pass and the September 10 corrections. Anyone comparing the tank's launch footage to current games needs to account for that sequence. The first patch is not the only point at which the hero's behavior changed.

Blizzard says September 8 replay codes remain available for this hotfix. That statement belongs to September 17; later code availability should still be checked against later patches. For a practical test, use the correct mode and current client, then compare survivability and time spent exposed rather than judging the entire hero from a single highlight. The linked official log is the reference for the full weapon and perk values.
