I can confirm, that there is a Bug.
For raiding it should be cast at 3-5 Maelstrom Weapon, but in most cases it wont.
condition Buff Stack Maelstrom Weapon bigger 3 also wont work.
I thought maybe Lightning Bolt iss Buggy - so i tried it with Chain lightning - same result.
So I am thinking, the Bot can not recognize the Maelstrom Weapon Buff.
Maybe it is like the Stormstrinke, wich has to be renamed in primal strike?
Maelstrom weapon maybe has another Name?
Sorry that I can not help more.
