Aloy is much preferred as a Burst Support over Main DPS as getting coil stacks for her Cryo infusion can be quite unreliable. Aloy needs 4 coil stacks to get the Cryo infusion and you can only get 1 stack every 0.1 seconds which is quite hard to do considering the Bomblets are scattered all over the place. One thing to note regarding Aloy's coil stacks is that **she can still get coil stacks even when she's off-field.
Aloy is very niche as she only performs well in certain comps and even then, she's still completely replaceable by other characters. She can be utilized on a Freeze team where she can be a battery and nuke at the same time since she provides 5 Cryo particles on her Skill. She can also be utilized on a Melt team where you can Melt her Burst for quite a decent amount of damage.
