The Reaper

I'm talking about the Forgeworld Reaper -
https://www.forgeworld.co.uk/en-GB/Dark-Eldar-Reaper

We're looking at a ravager hull with one gun that has two modes -
36" S7 one shot that inflicts D3 Haywire on a vehicle + ID toughness targets on a 5+
24" S5 large blast with Haywire

Just looking at it on paper, it seems like it could be an effective tool in our Dark Eldar lineup -
You have D3 haywire for when you need to deal with vehicles.
You can deal with Monstrous Creatures which suffer ID on a 5+.
Groups of vehicles can be hit with the large blast haywire.

With Nightshields, this thing costs slightly more than Haywire/Blaster Scourges.

Now the question is, is this worthy of bringing to the fight or has it flunked out?
