My Bow Tank Max HP Regen Mara - Want Feeback Comments

This is my first marauder build. Comment on it. Stats are as follows.
300 STR
194 DEX
301% Max HP
4.8% Base Life Regen Without Gear
50% Elemental Resist
104% Armor
104% Energy Shield
Resolute Technique
Iron Grip
+60% Projectile Damage plus as a bonus it increases all your elemental projectile damage from the Iron Grip bonus.

I'm using Poison Arrow+LMP, and Rain Of Arrows+Life On Hit+Life Leach+Blood Magic, and a Rejuvenation Totem to stack all that life regen in pvp. I'm also using anger and hatred auras, What do you think is this a viable pvp build? Comment.

Forgot to post my passive tree.
