WoW Classic, Gnome Glitch In Arathi Basin (Patreon)

Arathi Basin has just been released in WoW classic. The implementation seems to be flawed. 

The farm building has an uneven floor where grass terrain shows through. Gnomes can enter the fireplace (with a little wriggling to get right inside). Inside the fireplace pets/minions cannot enter or attack, other races cannot enter, and only auto-attacks can pass through. Effectively a gnome player can run into the fireplace and be invincible.

The fireplace is cosmetic only, the fire causes no damage to players.

This sounds like a minor trick, but it is actually very powerful in practice, because the enemy players tend to cluster around the fireplace using various unsuccessful methods to get in at you, while your team cap the other flags. Moreover the enemy faction can't leave the base without you capping it. Warlocks and frost mages can harass the enemy with their minion/elemental remotely.

It takes a bit of practice to get in and out quickly-a priest may be able to trap players who don't know this inside using mind control.
