Don't they have 8 MR ? And no armour to buff ?

Might reduce their survivability in the late game a touch.

Spells like Wooden Warriors or Army of Lead give units a set armor number, so I don't think I understand your question.

And the MR 8 is a weakness, but nothing is perfect. The fact that you can use Mass Regeneration and use them with a heavy evoking strategy more than makes up for it. I mean, if you send a few thugs to attack rear you can draw MR-targetting spells off the weaker units. Its basic strategy.
