Weather Druid - Viable?

[RaizielDragon]

How viable is a Druid with a focus on weather effects for battlefield control? I'm thinking things like fog, wind, rain, lightning, etc., used to control, move, hinder, and/or blind enemies. I know that such a build would be kind of party-dependent (because fog typically blocks line of sight in both directions), but if the party were ok with it, and properly prepared for it, is it a viable build? I'm not sure how many weather-based spells/effects there are, so I'm not sure if there is even enough here to focus on.

Storm Druid is very, very good at battlefeild control and blasting via weather effects.

I've built stormlords before, and honestly the best base I've found for them are Sorcerers. Everybody else gets too much extra stuff that has to be ignored for the core concept to remain the center of attention.

I respectfully disagree. Druids can eventually turn into their own storm (i.e. Air elemental) and rain down lightning with impunity. I think it's a perfect fit.
