Need some critique on my gear/gems/enchants

Stats:
148k HP unbuffed I think
11.94% dodge
13.29% parry
49.82% block

Trinkets: Impetuous Query (non-heroic), Mirror of Broken Images, Symbiotic Worm, Porcelain Crab.

The main thing I'm worried about is dropping too much stam for mastery which is why for red sockets I've yet to switch over to parry/mastery gems. Although hitting 25 Mastery would be nice (its close to 60% block).

As for gear upgrades I'm coming close to purchasing my T11 gloves or should I save the VP for the legs? As for the belt I can either hope for the Omnotron one or craft the Elementium one (tradeoff is one socket really).

Works beautifully together for me.

You're sitting at 170k hp raidbuffed so no need to worry about that until hardmode progression.

VP: wait for this week Algaloth kill and buy panties first, you'll get another 60 stamina from upgrading to the bigger enchant and they offer huge bonus on avoidance (parry instead of hit rating), too.

Belt: i love the crafted one, there will be a socket slot with 4.0.6 as well - but if you can get your hands on the Omnotron.. it's just as good.

Think I should change any gems or just stick with what I have?

Thanks for the suggestions I will take a look at the T11 Tank Legs.
