Guild Wars 2

One of the key aspect of the end of the living story s2 was the fact that the sylvari actually minions of Mordremoth and the dream is the vail that conceal it. What if at the fight against Mordremoth the dragon will cast a debuff on a random sylvari character, this debuff will cause the character to attack allys for about 5 sec, lats call it Mordremoth calling. When the debuff will be over the character will receive a buff that will increase might, quickness, and fury for about 10 seconds, lats call it ventary’s retribution. The skill will have a long cooldown so it will not be a frustrating skill. I think that a skill like that can capture what most NPC feel about the sylvari in the expansion.

No one will want to party with sylvari characters then. It creates mechanical separation of players, which a net had repeatedly stated they did not want to do (hence the whole peace treaty between charr and humans).
