Nice Marauder Jewel

So i though this would be good.

Total if all nodes allocated:

Gain 1 Endurance charge every second if hit recently
15% change to gain Power Charge on Critical Strike
80% increased evasion rating
24% increased Armour per Endurance Charge
80% increased Armour
160% increased Melee Physical Damage
80% increased Physical Damage
50% increased mana regeneration
10% increased Max life
160% increased Lighting Damage with Attack Skills
80% change to avoid being chilled
60% increased effect on chill

I dont play with Marauder, but the location of these nodes makes sense.

Any thoughs is this usable?
