[Spell] Shaman - 187880 - Maelstrom Weapon

[Belebacsi]

Spell
https://www.wowhead.com/spell=187880/maelstrom-weapon

Class & Specialization
Shaman - Enhancement

Describe the bug
I don't get Maelstrom weapon stacks, but the UI visuals for them appear

Expected behavior
Should give stacks that make casts instant

Criticality
[ ] Breaking class : The class/spec isn't playable without this spell fixed. (Taunt for a tank, Mage's Fireball doing 0 damage, ...)
