Make Nekros's Shadows Of The Dead A Toggle (Suggestion)

[TaylorsContraction]

I've recently been leveling my Nekros again and I constantly  notice how squishy he is. 2 is a huge life saver but it must be followed by 4 to give ample cover for the retreat to cover.

 

What I really would like is that 4 was a toggle rather than had a duration at all. I use mana to summon these undead, they will persist until killed or until I hit 4 again to despawn them. Nekros really needs to have some beefcakes along with him to soak up damage but it's not very mana effective to cast this over and over. A lot of times the summons won't even follow you because you just crossed a large gap or something. Anyways I think this would be a nice boon that isn't overpowered since the summons can still be killed. I imagine more experienced players may see some problems with this mechanic for Nekros's 4th skill and I'd like to hear why.

 

The only thing that sprung to my mind is reviving an ancient healer or some cool mob that has an aura, but even then I don't think it's a big deal.
