Need some help with E/W

OK i am going back to e/w after a while with a e/mo, i just like the /w part better.

So i want to build a defensive ward build but still have some attack.

Ward against melee
Obsidian Flesh {E}
Healing sig
After shock
Obsidian Flame
Stone dagger
Crystal wave
deflect arrows

With this i have 75% to deflect arrow, 50% to block melee, and can not be targeted by spells. My healing will lack as only sig, also no res here.
Please let me know what to change i am open to anything including change seconday if i had too.

i have a great gold earth staff with +5 armor +15 energy and recharg 10%, but should i use a wand and a tactic shield?

Do you really need to tank? whats your goal pvp or pve?

pvp, and its not pure tank i could through on armor of earth and kinetic and just spam stone daggers every 5-8 sec if that was the case

I shoulda said 4vs4 of 8v8 but the point is that I would go more ward support. such as ranger spike. Taking WvE would help the dmg from kindle. Wagainst foes is great so that your team can snare an enemy team or slow the flag runner if its GvG. No point of aftershock without earthquake IMO but obs flame is all i would carry offensively.

If this is for 8v8, drop Healing Signet, AS, CW and Deflect Arrows, grab Ward vs Foes, "Shield's Up!", "Watch Yourself!" and Iron Mist.

WvF is pretty basic, slows squishy targets, and enemy Warriors.
Shield's Up! for when against Ranger Spike.
Watch Yourself always, +20 armor is always nice.
IM to stop enemy Warriors for from catching your Monk.

If this is for 4v4, drop CW and DA, grab Earthquake and Res Sig.
