Guild Wars 2

I am confused about the efficiency of condition stacks particularly against high hp mobs.

I am not sure how to explain it, so I will just describe a scenario and as to why this confuses me:

A 5 man party takes on a heavy hp mob champion. of the 5, 4 are condition (bleed/poison) build necros or thieves or engineers. The party essentially attacks the champion and its condition stack in bleeds is 25.

thief 1 deals w in bleed damage per tick
necro 2 deals x in bleed damage per tick
engineer 3 deals y in bleed damage per tick
thief 2 deals z in bleed damage per tick

Considering that the bleed stack is at 25, and that is contributed by the 4 in party.

What amount of damage is tracked, or is it tracked to the last hit

Is the bleed condition effectively a single amount of damage even though multiple attackers may contribute w,x,y,z bleed damage when topped out at 25 stacks?

Another scenario is in if 4 players are each able to dish out over 15 stacks of bleed in their cycled attacks, and considering that the bleed stack caps at 25..what happens and is the excess omitted?

Please explain.

The explanation will likely change or solidify a bleed build player’s decision in play style and preference.

Condition builds are weak for pve because of that. If a mob that you are atacking is already with 25 stacks you will do no damage with bleeding. So in group events for example all the players with condition builds will be limited to that 25 stacks, all that 25 stacks are shared among the players involved in the event.

So, for dungeons and pve condition builds suck.

It is not only the condition classes that use this stack, every power build with 5 trait points in the precision line produces also a lot of weak bleeds as well.
It is a first come first serve, so it isn’t even guaranteed that strong condition DD will bring their bleed on the mob as well.

Additionally for burning and poison there is only one stack for all players.

And therefor bringing more than 1 Condi into a dungeon is useless, because every build can generate at least 15 bleeds plus poison and/or burning.

The exact mechanics of conditions have yet to be found out by players, especially the multiple stacking or the cap stacking are still clouded.

Right now the current mechanics are assumed to be like this:
Once a tick based effect is inflicted on an entity a tick counter starts. Every second (probably half-second for torment) that counter checks for current conditions and applies their damage. This allows even for 3.1s bleeding to tick for times.
For duration stacking conditions each source is checked and the strongest one applied (and reduced time).
