When used properly and in co-ordination with your healers, Double Edge L can increase your damage tremendously and when optimised is unrivalled in its potential damage output. When used improperly, it will decrease your damage tremendously because a dead player does no damage.
Basic Usage
Before using Double Edge L you should always check that you have sufficient healing available to keep you alive at higher stacks. If you intend to use it during a BA run, always ask your healers first before equipping it, as without their help you will not be able to make proper use of this action and would be better off taking something else instead.
You should always pair Double Edge L with an appropriate Wisdom for your role: Wisdom of the Martialist for Tanks or Wisdom of the Duelist for Melee DPS.
While it might seem tempting to pair Double Edge L with an action like Bloodbath L for sustainability, you will always do more damage just by having an appropriate wisdom and performing your normal rotation well. The flat damage gain from the Wisdoms should not be overlooked.
The damage taken from Double Edge L is not only the responsibility of the healer to mitigate, the user can contribute a lot in making it safe to use as well. As a Double Edge L user, you should always be using the highest ilvl buff food you can obtain for the maximum vitality bonus, and using Eurekan Potions on cooldown. You should activate your first Eurekan Potion 5 seconds after activating Double Edge L as the healing effect only lasts 40s and the damage taken from the first few stacks is minimal compared to when at the full 16 stacks.
The most dangerous time when using Double Edge L is when you are at high stacks and there is incoming damage, e.g from a raidwide AoE. The overlapping damage from a tick and the AoE could kill you outright, and so you should always be paying careful attention to your HP. It's always better to be cautious than risk dying, the damage lost from a death will always outweigh any potential gain. Every Double Edge L user should have a macro on their hotbar to remove the buff, or be ready to click it off manually from their debuff bar. An example macro would be:
English:
/statusoff "Double Edge L"
German:
/statusoff "Logos-Zweischneid"
French:
/statusoff "Évocation Logos: Double tranchant"
