Have a look over at his forum post. A few opinions on him there.
I personally think he’s a top 3*. Def down with dispelling consequences is always a nice touch & the wither effect stacks & can get quite nasty for the enemy on top of his def down. We can’t forget the boosted health removal which I think is unnecessary above 30% for 2 or more family members, heck 30% is a lot just for 1. I’d say 10, 15 & 25% removal max. Anything above that is getting a bit insane ! All in all tho he’s a top tier 3* IMO.
