Guild Wars 2

So I’m not sure about them. 2 and 4. Poison Volley doesn’t seem to do much damage even if I hit all 5 on the same target. About 4, big bosses always have 25 bleeds on them anyway.

Am I missing something? Are they even worth using?

For damage, no.
For utility, yes.

Poison lowers healskills effectiveness so in pvp pay attention to the counterparts healthbar and inflict poison on him to the right time. 4 is a cripple. Simple as that, usefull in pvp again. For pve your mostly alright with #1
