Well you may not know since you pick journeymen during post-game, not pre-game. Even so if you think a journey skink isn't worth it, then you'll stop your opponent getting 60k of inducements.
I think those who have a problem with journeymen play in leagues with fixed schedules, so they know who they are gonna play next and can plan accordingly. (Correct me if I'm wrong?)
Now if people are whining that journeyelves are too good, then I suggest they play in an
open (bashy) league where elf players are likely to come up against a bash team when needing journeymen. Yeah, AG 4 journeyelves are a damn site better than a snot or zombie, but if you need journeymen, then you've only 11 players and if you've 11 players, it only takes 1 failed KO roll or a CAS to be a man down and in my experience, once you lose players, you often lose more players. (Ok longbeards are possibly still a problem as an 11 man dwarf team can easily end the game with 11 players, although if they lose players they are in more trouble than quicker teams so I don't think it's a huge problem).
If people play in scheduled leagues (which is itself a houserule!) then journeymen may need to be "fixed", in open leagues, they don't.
