flail vs knout vs scourge

[echodrome]

I've noticed more people prefer flails over the other two upgraded versions. Is there a reason? Wouldn't the other two produce more damage (i.e., better leech) for the same speed and what not?

Lower requirements, like dexterity and strength. That's pretty much all there is to it.

The Flail tends to be used for runewords that aren't meant for (or used for, anyway) melee attacking, such as HotO. The lower strength and dexterity requirements means it can be used by more characters without investing points into those stats.

CTAs are used in normal (i.e. not exceptional or elite) items for the same reason.
