It's the big line between having a lot of choices and the reasonability of implementing the choices in a way that have an impact. I would like a lot of choices but the more choices we get the less viable it is to get little things like going "By [the correct deity]", regardless of whether all lines are voiced or not.
We need at least new gods for the Tempest domain. Talos isn't really interesting though because his Clerics just want to destroy everything. And Umberlee is also evil. There should be some deity associated with winds, air and the elements. Freedom and such. Thunder is a force of nature and shouldn't be "evil only".
To be fair, "thunder" is one of those forces of nature that is kinda hard to put a non-destructive twist on, like volcanic eruptions or draughts. Even real life deities like Thor (who is the literal personification of thunder, that's what the name Thor means) it's used as a negative personality trait, for humour at best.
