In-game Hurricane/Hydra bug for Thresh
Before the patch 5.22 Thresh
could use Hurricane
and not the Titanic/Ravenous Hydra.
But afterwards it says that Hurricane is only for ranged champions while on the other hand you can get the Titanic/Ravenous Hydra - but you can't use it's active.
Not sure if Thresh will benefits from the passive from Hydra, but perhaps something you could look into.
