I was recently looking through all the spells available to do CC and I realized that an organized system of dropping CC can actually lock an area down almost indefinitely. In certain areas, and in certain chokes this would be similar to early AE stun in DAOC.
One example. A group with 3 elementalists.
We need to test the mechanics of lightning hammer, but assuming that you can summon a hammer and swap out the utility skill without losing the summoned hammer, this should be ok to use without messing up anyone's utility skills.
If each Ele summons a hammer for a melee to use during the beginning of the fight, that gives each melee access to Static Field. This is a lightning field (lasts for 4 seconds) that will stun anyone in it for 3 seconds. Each elementalist that has staff equipped also has access to a static field. That group now has 6 X 4 seconds of lightning fields that can be applied.
In a choke point that could mean near perma stun for all enemies in the area for almost 30 seconds. The cooldown on the Lightning Hammer's Static field is 25 seconds, the Elementalists is 40. So one or two melee could not drop the hammer after dropping their first lightning field, and follow up with another, extending the period to over 30 seconds. Or a larger area can be locked down for 12-16 seconds.
Leap finishers inside of Lightning fields cause Daze.
We need to test the AE range of the Daze effect in this situation
Daze locks out abilities so you can't use them. The Lightning Hammer has a 600 range Leap finisher on a 6 second cooldown. So for example, if the Daze lasts 2 seconds from the finisher, that means 3 melees with Lightning Hammers can keep Daze up 100% of the time in a lightning field. Of course, that is dependent on the radius of the Daze caused by the leap finisher, and also by the duration of the Daze. If its a 1 seconds, you'd need 6 melee cycling the finisher.
But even with 3 cycling a 1 second daze, that's 50% of the time daze is up. With the Lightning Fields kept up as long as they are, that is a huge force multiplier for the melee.
And if the choke is in the right spot, we can avoid a lot of the ranged dmg from LoS as well.
I will be playing an Elementalist quite a bit next BWE so I plan on testing the Lightning Hammer mechanics. It may even by that an ele can have a Lightning Hammer equipped, Drop a Static Field, then drop it to go back to Staff and drop another Static Field.
If so, a lightning field could be kept up for even longer, or more lightning fields could be sustained at once.
