Pve giant killer build need help

I need to make a hero that can stop named gaints from turing my party into pancakes, my guess is the mesmer can do this what would be best combo for turning gaints into weaklings and spell lineup.

Those named giants in eyes of the north can hit very hard lol.

Ward against Melee, Ward of Stability, Enfeebling Blood, Ineptitude, e-management on a mesmer, maybe Weapon of Quickening from a hero so they can use wards almost all the time.

[skill]Spiteful Spirit[/skill][skill]Reckless Haste[/skill][skill]Enfeebling Blood[/skill] on 2 curse necros.

Then take Lo Sha for Ineptitude and Herta for Ward Against Melee.

And don't aggro more than one group of those.

Works fine for me in hard mode.
