Question of the Week - Which profession mechanics best mesh with their theme?
Also this post is very interesting, I particularly found this information useful.
Some effects stack via duration and some stack via effectiveness. Removing a condition will remove it entirely, stacks and all. There are various other effects that are generally profession specific like Frenzy and Frosty Armour that I won’t cover since they are less prevalent than the more common ones.
Damage in Guild Wars 2 is not exclusively dealt by hitting people in the face with a hammer. There are conditions that damage that weapons rely on. There are also conditions that make hitting people in the face with a hammer deal more damage!
Bleeding – stacks in intensity meaning the more something is bleeding the more damage per second that they take.
Burning – stacks in duration meaning the more something is burning, the more seconds it takes damage.
Confusion – stacks in intensity. This condition damages the victim every time they use a skill. In PvE the AI will not stop attacking making this a damage condition. In PvP it can operate as a slightly defensive condition.
Poison – stacks in duration. This inflicts damage per second and reduces the effectiveness of outgoing heals so the victim will find it difficult to heal himself/herself.
Vulnerability – stacks in intensity. This reduces the target’s armour.
