Guild Wars 2

should i spam signet of spite? I mean if you spec in signet the cooldown is 48.

Is the condition applied worth it, or should I just don’t active it since the passive is more power.

Most of those conditions should already be on the target. You only miss maybe poison and blind. But poison could be applied by a thief. Same with blind. So its almost never worth it. Also in downscaled dungeons where there is a stat cap. Signets ignore the stat cap. So they are worth keeping a lot of the time.
