0.4 Empowered Zombie creating 2 normal one is not very good

Patch note for 0.4

"

Raise Zombie: Creating a Zombie from a Power Charge now also creates 2 additional non-empowered Zombies. Empowered Zombie now deals 122-253% more damage with Hits at Gem levels 5-20 (previously 100).

Problem 1:
I initially thought this would be great, but now it is almost impossible to have 4-5 empowered zombie hitting a boss because the normal zombies just get in the way. It would be nice to be able to disable that behaviour or make it into a support gem instead.

Problem 2:
You can't have more than 4 empowered zombie, because the normal ones will replace your last created empowered one. It would be nice if stronger zombies don't get replaced by weaker one.

I feel adding a slam ability like PoE1 would have been a better design if the idea was to improve the clear by having more zombies.

TLDR: The 2 normal zombie summoned is annoying because it blocks the path for the already slow moving empowered zombies
