Is Hex worth it at high levels?

No, it's a call back to the discussion on RAW vs RAI vs RAG - RAW isn't the holy text some folks believe it is.

Funny... I would think that those that absolutely insist that their houserules are not houserules but are in fact rulings would be the ones who think RAW is a holy text. What's so bad with saying "I don't like that the Hex curse can be shifted silently, so I'm going to add a rule that says you need to speak some words to do it?"

It also has the advantage of keeping it contained. If it's a houserule, it applies ad hoc to Hex (and we can then debate the merits of the houserule, whether Warlocks need the nerf, etc.) If it's a ruling with systemic consequences, you have to deal with it through all spells, all transformations that might hinder your ability to speak, etc...
