A party still doesn't have a good reason to go beyond the holy trinity of Tank / Nuke / Heal.
Especially considering the huge buffs given to those.
Here's a suggestion:
Cry of Pain - Interrupt target foe's Skill. If a Skill was interrupted, all of target foe's Skills are disabled for 10 seconds. If that foe was suffering from a Mesmer Hex, that foe and all foes in the area take 40...88 damage.
- 1 second or 3/4 second cast time, making high Fast Casting a serious plus, so this doesn't just get picked by any profession.
- Other costs remain the same.
Ether Nightmare - You and target foe lose all energy. For every 10 points of energy lost this way, that foe and all foes in the area suffer -1 energy degeneration for 4...7 seconds.
- Costs remain the same.
Which party wouldn't want to have one pesky AI Monk's skills disabled for 10 seconds and an AI Elementalist's near-infinite energy used against him and his party?
