New Mechanic: Doublecast Skills
A doublecast skill is a new type of spell that casts on you as well as your target. By utilizing proper positioning, skilled players can significantly increase the power level of these skills as well as the area that they cover. Many of these skills were reworked because they were too unwieldy to play normally due to conditionals or poor synergies with other skills. In the case of Mirror of Ice, the skill was providing too much power in PvP without being useful in PvE.
New Functionality
In addition to doublecast skills, we are also allowing some Elementalist elites to have functionality usually covered by other professions. Because these skills are elite, we feel it's OK to blur the role of the Elementalist a bit, as long as this functionality meshes with how the Elementalist normally plays.
Example: Mist Form
While its previous effect was fairly strong against martial professions, Mist Form had almost no effect against casters, and its one-dimensional functionality made it a difficult choice to take over most damage-dealing elites. It could also be very frustrating to use without removal. This update changes the skill into a defensive skill that also provides healing to your allies. In order to emphasize the Elementalist nature of the skill, though, the healing and damage reduction conditionals encourage offensive spell use. To prevent stacking in PvP, this skill has been split.
New Synergies
We're also making a few smaller changes to some skills that we hope will promote some new synergies and help make some previously nonviable builds possible.
