There are so many broken/weak things in all games. You can ignore that skill if you find broken. It's simple as that. For me bigger problem is 2H warriors. I'm not a pro in this game or have ridiculous items. I'm still using Lohar's Hammer at level 15 in Tactician. Put all my point into strength, two-handed and warfare and 2 into necro. With Executioner I can kill 2 enemy in first turn without pre-buff and all that stuff.
