From all the main 4 factions, not including mixed (Bandits - Shadow/Fire, Stonekin etc..), Shadow is the only one with a single melee T4 unit - Overlord. 

All others have a fairly mixed selection pool when it comes to T4 units, where Shadow is predominantly ranged. 

Maybe a big undead/beast type unit would be fitting, similar to Forest Elder. 

You can maybe also post your suggestion in this thread, people have collected quite a bunch there already 🙂

I did not see this section 😮

 Thanks for the suggestion, will do!

It is on our wishlist to have a tier 4 melee Shadow unit at some point down the line, but nothing concrete to share yet.
