another example: share the power
why sharing power, if there is no reason to? it doesn't takes effect.

in the tooltip you can see many listed times: the time it needs for cooldown, activation time, duration, dot, hot, and last but not least the time that's not listed: the time, the character needs to activate the skill after activation time.
another way is, to use the debuffs on the enemies. but i think, this one is not supported, although it would be the better way.

if one of this ways can be used by an addon, it would be great to read about it.

sorry for that bad english.

hope to hear from you.

so far

Plugins can not disable/deactivate skills.
