I act as our pseudo-PG most of the time (our actual PGs are a rare sight). So it often falls to me to introduce someone to the game, or play against them for their first couple games at our LGS with. I also tend to give out advice and often try to talk strategy with the newer players after our games.
The end result is that more than a couple Khadorans have come through our doors with the battlebox, or their hearts set on MoW, Karchev or other similar aspects of our faction and I'll be the one who tries to help them grow as a player. After watching a newer player struggle with Karchev to the point of almost complete desperation, and having had a similar experience myself with Karchev specifically, MoWs and our jacks generally, I'd like prevent this from occurring again. Overall, I've been quite successful with Khador, placing in several local tourneys, etc. However I've mostly utilized our light infantry to achieve this.
The other day, a newer player and I were talking, and I said to him "If you want to play jack heavy, you should play Protectorate." This was IMO truthful but too blunt. I've fielded jack heavy lists upon occasion, and have even had success with them. But I would not encourage a player to pursue it as their primary playstyle within Khador.
As the forum has seen over the past year, this is not an unusual phenomenon.
So my question for the community is this: Assuming the player is receptive, how do you go about encouraging them to spend their money and time branching away from what brought them into the faction?
