I can confirm that orc chieftain recruitment does NOT work.

I have orcs, orc trackers, and orc veterans and recruitment does not increase the numbers of any of the three after several battles done.

I also have open reserve slots.... So yah unfortunately this seems to be bugged

Do you have less of these orc units then what your Leadership allows? I'm just guessing, but I'd assume this only works if your troops are not maxed out.

No. It simply doesn't work for Orcs, but works for Goblins.

It is hinted that this is fixed in the Beta Patch.

That said, recruitment works regardless of leadership.

e.g. it will happily put you into "Out of Control" mode. A little annoying at times, but quite a handy mobile way to "top off" your units as you level up and get more leadership items.

Another really stupid bug/feature is Scold.

Scold requires other orc stacks to be in the field, but it only works on your OWN stack. <rolls eyes>

Maybe they expected people to have dual stack orc veterans. <shrugs>

Nah, it means your Orcs vent their anger only on other orcs. :) It's a racially sensitive orcish thing, you see... :)
