Dim Vision revisited

So far my Necro has 21 in Dim Vision with + items. Since I had no
experience before I use this skill I think a level 18 to 20 would be fair
since a level 21 will cover about half of a screen. I will cast Amplify
Damage over a group of champions then DV and the champions will still be
amplify damage while the normal monsters will stand doing nothing. These
darts thrower are annoying so I will DV them and will cast AD not on the
monsters since the area of my AD (1 point) is greater with + item but just
below them to catch the first row with AD while the one in the back are
still curse with DV. So the army and the Necro get less pressure from these
annoying thrower or peas shoother.

Also I did not have the time to reply to the guy who posted about his Necro
build in the thread "Newbie Necromancer question". I do not agree about
maxing Summon Resist or put more point in Amplify Damage but this guy had a
good point. I would never max Skell Mage since they attack different target
but did the guy said he was teleporting on the monsters? This is when I
lighted up. When I play around Iron Maiden OK who will kill my merc or my
army so easily with the curse I simply cast DV all around and since the OK
are not be affected I cast AD or Decrepify and recast DV for the normal
monsters near the OK. I switch to my tele weapon then tele on each IK one
after the other. I must say that in Hardcore it is a strange feeling since
all these monsters are around the Necro and they would kil me if they where
not under the curse of DM.

I would prefer to tele without switching weapon since I lose my resist,
shield and +skill from my main weapon but I always do it on hell Baal with
one or two cold mage then I cast decrepify and I wait.Since all the army are
attacking the same guy and none are in the back doing nothing I imagine than
maxing the mage would be good for a tele build Necro.
