Arc Warden - support

Is helm of the dominator on Arc Warden a good idea? In the current meta with ult and 2 dominated creeps for example:
+ Lycan with his wolves, Kobold Foreman (Neutral creep)'s speed aura and one more creep's aura + Nature's Prophet 's treants.
And with AW's slow and dmg it can be a very dominating game.

Hi, friendly neighbourhood Arc spammer here.

The first thing you notice about the Self is that it's an absolute mess of bugs - quickbuy, numerous items, hero interactions, pretty much everything you can think of has a bug in it.

HotD is one of those bugs. If the main Zet has dominated a creep, then spawns a double, and the double dominates another creep, the main Zet's dominated creep will die. So the item flat-out doesn't work properly.

Even aside from that, it wouldn't be worth buying though. Arc teleports around the map too much for creeps to really follow him anywhere.
