Demesne effects will be faster now. Also, the formula for how long the demesne effects hang around was changed. Originally (like a year ago) we coded things to get beefed up by a parent skill. (*Not* to be confused with a specialization. Elemenatlism is not the "parent" of Aquamancy; Aquamancy is rather a form of Elementalism.) Planar is the parent of Elementalism (and its specialized forms), so it was originally using skill ranks in Planar alone to determine how long your demesne spells last. Long ago we changed that design, but demesnes got overlooked.

The final design for skillset boosts, which is commonly used elsewhere in nearly every skillset, is that the parent skillset provides a mild boost but the main skill gives a large boost. For example, increased Tailoring makes you sew longer lasting items, and increased Arts will also give a mild boost to the durability of what you sew; that's a very common theme throughout the skillsets. This means that skill ranks in Elementalism will give a strong boost to the length of time for your demesne spells, while Planar will give only a nominal boost. For those of you who have not transed Planar, this means that your demesne spells will last longer then previously and thus should be viewed as an upgrade.
