I first voted no just because in current meta slow heroes are really far behind.
But I quickly changed the vote.
He is superior to all the legendary classic red heroes (cross Marjana out, it’s apples vs oranges with her), no doubts. Better than some of the HotMs and event heroes also. Red just lacks good fire power, and as others outlined, there are hardly any chances for a good red hero to be pulled until July when fingers crossed we are getting someone decent.
He won’t be gamechanger against your Telluria battles - if you have a board decent enough to charge a slow hero under Telluria, then likely with any other hero you’d be already winning. But he will help elsewhere.
