Enhance with 2h Weapon in 11.1?

[Adelaide-proudmoore (Adelaide)]

They explain it in the patch notes you linked:

@Linxy

Stormstrike is now learned at level 10 (was a talent).

• Developers’ notes: The primary resource system, Maelstrom Weapon, was not very noticeable as a passive in the spell book. To address this, we’re making Stormstrike the introductory ability for those choosing the Enhancement specialization and replacing its spot on the talent tree with Maelstrom Weapon. Alongside this update, we’re allowing Stormstrike to be cast without an offhand weapon for the new player experience.

It’s so if new players hit level 10 they can go enhance even if they don’t have an offhand yet.
