Where are all the rookies?

I want a journeyman warcaster stack for protectorate. Like one of the other nations journeyman gets captured and wracked

Even Rorsh who is 3 Fury has double control area with Brine.

Isn't the Druid Wilder a warlock-in-training? Actually I thought all Blackclads were potential warlocks if they worked hard enough.

That assumes there are generic, nameless rookie casters/locks. But if a faction has only a small supply of new casters/locks, even the Journeymen may well be named and special characters. From what we've seen from young casters in the fluff, all of them have different abilities.

Cygnar trains its journeymen in a (fairly) standardised way, which enables generic journeymen with identical abilities in game terms. Although even in Cygnar there some journeymen have their own talents (think Jakes, or the new caster discovered in Aftershock). I wonder if the faction which might actually be closest to Cygnar would be the Skorne, as their warlock abilities are apparently an extension of mortitheurgy, which is taught and studied. But then that gets modified by house and caste status.

Other factions (and probably best to exclude mercs/minions here) might not have that kind of standardised training, so all of their casters, even the most junior, might have different abilities. That might be more pronounced if a faction permits its juniors to play to their strengths (Una1 would be an example - she clearly has an affinity for particular beasts, and the Circle accommodates that), or if training is more on an apprenticeship model from the beginning (where casters might pick up non-standard abilities from their mentor).

From what we've seen so far for training (mainly in Rites of Passage):

• The Aiakos story suggests that in Cryx identifying anyone with 'caster talent (or at least, anyone living - this is Cryx, after all) is rare and such individuals are instantly in some sense 'special'. Aiakos is also largely left to figure things out on his own - but Cryx is in a more or less permanent state of low-level conflict with everyone (including each other) and has a very Darwinian society. Training or apprenticeship would just mean putting effort into creating a rival;
  

• Khador varies a bit. Sorscha apparently had some kind of apprenticeship
  with Vlad. But this isn't mentioned for Malakov, who was instead trained
  at the Druzinha (presumably with arcane training via the Greylords).
  That might be a timing issue - maybe Malakov is rushed into the
  frontlines independently due to the pressures and multiple fronts Khador
  experienced towards the end of the Mk2 fluff, and that normally he
  would have also had an apprenticeship too;
  
• For the Protectorate, their Choir is meant to be how potential casters are identified, and that worked for Durant. It's difficult to tell if his story is typical, as he was discovered while part of an active Crusade, but even then he was taken out of combat roles for his training. That training was apprenticeship based, rather than standardised. 
  

The Protectorate sends captured arcanists to be Vassals (and apparently actively tries to capture them). Menites with magical abilities apparently also voluntarily become Vassals. Presumably such Menites might then be identified as potential warcasters from their work with mechanika and cortexes. We haven't yet seen that in the background, but a special connection to mechanika is something that can identify a potential warcaster (mentioned in relation to Alison Jakes).

If Maddox is typical, captured warcasters aren't trusted to do anything other than be tortured and imprisoned.But then captured warcasters are all captured officers with potentially very valuable information, so that makes sense (see also Vindictus torturing Vlad).
