I made this, after I felt that the Elementalist lacks a lot of versatility compared to other professions that we know now. I am not sure if I got all ground targeted skills right, but even if I misplaced one or two, you ´can see a trend.
After going through the list of skills (and I took weapon skills only), I saw some "balance" issue with Fire magic. A lot of skills focus on the burning condition, while Water and Air offer a little more variety. The focus on area effect with Fire that needs to be timed a lot (especially Burning Speed, Burning Retreat and Backdraft) means that a player playing a Fire Elementalist needs to move around the battlefield a lot more that attuning to Water or Air will demand.
Since you can change your attunements in battle this might not be a big deal, but worth thinking about.
