"Worst" Unit

[Laman]

What is in your opinion the "worst" or least useful unit, and why do you think so?

Personally I would say Pantodapoi.

The Good: They are numerous and cheap, so are relatively useful as garrison troops.
The Bad: They can't fight, sure their attack isn't to bad relatively, but they have no armor, no skill and a shield that is useless and provides almost no protection against arrows (or anything else for that matter).

Edit: It seems it became "wors" unit. Well could be worse.
