Diversion

Description
For 6 seconds, the next time target foe uses a skill, that skill takes an additional 10...47 seconds to recharge.

Usage Notes
Diversion dumps additional recharge time on top of the skill's innate recharge time. Diversion is best used to slow down a fast activating skill for an enemy. This has many powerful applications:
 * Shutdown a monk's Orison of Healing. Orison does not heal a lot, but it's power in that it casts quickly and recharges quickly (2 seconds). An Orison that takes 30 seconds to recharge is useless to a monk.
 * Take out an elementalist's pet attack. Most elementalists will have a pet spell for doing damage repeatedly while their big nuking spells recharge. For example, Aftershock for Earth Magic users, or Fireball for Fire Magic users. Diversion can make these take nearly a minute to recharge.
 * Taking out a potential threat from warriors and rangers. Warriors have skills like Savage Slash and Disrupting Chop and rangers have skills like Savage Shot and Concussion Shot that can greatly bother a Mesmer by interrupting him/her. A mesmer can use diversion on them to make those attacks (which are dangerous because they recharge quickly) take a minute to recharge and thus become far less effective.
