Guild Wars 2

I have build a fully exoticed out necro that I use 3 builds on, either a Heal/Support conditionmance build specing 20 curse, 30 death, 20 blood, or a burst dmg/condition dmg staff hybrid speced 20 spite, 20 curse, 30 death. both offer protection 3x 4s long, constant condition removal and perma regen along with cripple, freezing, weakness, 15-20 stacks of bleeding, vulnerability and blind. My 3 build uses minions with the same 20 spite, 20 curse, 30 death. all I use staff and scepter/dagger on.

The debilitaing effects seem good for dmg mitigation, CC and keeping Dots up thru epidemic but the 2 boons I apply along with the 2 moderate hoT’s just are not cutting it for support in dungeons. So I want to build a support class based around longer duration of boons, sheilding, reflect and stun/dazing.

I usually run with a DPS warrior, DPS guardian, Turret engineer, and usually a necro being a either a MM or hybrid spec . This leave leaves 2 slots for support heavy builds.

Which would do better to fill in as support?

Water ele
Guardian
Mesmer

Please state your choice and give an example as to what it has to offer and why it would be the better support choice.

Tnak you.
