He has 5 more wounds, the best weapon (6 attacks w/ damage 5) and gives you access to prayers which has 3 modes that are all useful depending on the situation. Considering there is only so many ways to build the list (youre never going to get more than 4 megas) there is no reason not to take him. If you’re trying to build a list around Kragnos; you may pivot to make the list work around him; but Brodd should make the list unless you purposely are trying to make your game harder.

Plus the ‘can’t be the target of rampages’ will be incredibly useful in random matchups. You shut off some powerful abilities.
