Does 3 ticks of Fiddle's Drain not proc thunderlords?
I was playing Fiddles with thunderlords and it didn't seem to proc when I was draining them. Wouldn't be an issue, except that Morg's pool does, so I feel like Fid should as well.
PS: I don't think 1 spell should be able to proc all ticks, but if Morg gonna be allowed, I think others should as well.
