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

[Billythepancake]

AST AoE has range.
SCH AoE is PBAoE but instant cast.
WHM AoE is PBAoE but has stun.

Tradeoffs.

the range hardly helps though, SCH can weave in 2 abilities with each AoW and WHM stuns leading to enemies doing no damage. AST has to completely stop and heal. Giving them a slow to help them mitigate some damage so they can heal a little less and dps a little more hardly comes off as OP.
