Guild Wars 2

Direct damage currently scales with virtually every offensive stat except for condition damage/duration. Power, Precision, and Critical Damage stack together and work with vulnerability to hit for huge numbers, especially in PvE. Condition Damage tends to fall short except to counter high toughness, low vitality enemies. This contrast is even more apparent in PvE where the 25 stack caps on conditions are more likely to be met and duration-stacking conditions are often applied to the point of redundancy.

Simply put, Vulnerability should work with Bleeding, Burning, and Poison:

1) Vulnerability is currently one of the weakest conditions except in high stacks and/or with multiple allies.

2) Condition Damage tends to be lower than Direct Damage, especially in PvE.

3) Many CD builds apply Vulnerability to poor effect (Staff Mesmers, any Ranger with opening strike, a longbow, or a vuln pet, Necromancers, Warriors using an axe or GS, etc.) This change will help synergy within builds.

4) This improves offensive team synergy.
