Will it help if Astro have slow Effect add to Gravity?

[Seraphor]

I'd like Gravity to have a Draw In effect, plus Heavy.

So it has a 5y radius, but would add a 10y radius 5y Draw In effect, so that you move any enemies between 5 and 10y into range for your next Gravity spell. Bosses immune obviously.
This would help AoE dungeon pulls. Then the Heavy would help keep them in place.
