Few question about engenering in wow classic :

- Can you learn Gnomish engenering, unlearn and respeck Goblin and keep your Gnome stuff ?
- Saper Charge ? It does domage only to you, or you're whole group ?
- Ultrasafe Transporter vs Dimensional Ripper : What is the best for boxing purpose. I remember the fail was a teleport over a cliff on the gnome one (things that's annoying while boxing), and a dot on the goblin one (don't seems too bad, especially if you have a healer on your group)
- Do you think about some tricket or specific engenering stuff who scale well with a 5man boxing team ? Will you trade a slot of you're equipement for a engenering item outside of dungeon for one or more of your characters ?
