In general not much changed over the last few patches regarding the rotation.
In the German forum there are some old guides (and tons of discussions covering topics such as Ice Harpoon - yes or no? Autoakts yes or no? etc), but I didn't really consider them worth translating now. Considering your last run though I guess that you 'forgot' about some important skills while focussing on other skills with no importance:
you sort of didn't or hardly used these skills (though other good sorcerers use them frequently): Flame Spray (hardly used), Flame Harpoon, Big Magma Eruption
instead you focus on skills that you won't find anymore in most (single) situations - such as Delayed Blast, Meteorite, Delayed Heatwave...
In other instances than Narakkalli you'll often find Ice Sheet and Summon Whirlwinds as well to enhance the DPS.
