Greetings!
I've toyed around with the idea of introducing Kislevite allies in my Empire army, more for fluff and campaign reasons than for tournament play. I did some hunting and couldn't find in the 8th Ed. BRB that having the old allies rule isn't allowed anymore but seeing as how this was introduced back in 6th Ed. I'm not sure if it's allowable anymore for the reason it's so old.
My other questions is are they worth it? Looking in the 2004 Compendium where the list was published the main infantry block is rather nicely armed with bows and great axes and are allowed to stand and shoot no matter the range but they have no armor. This makes them rather squishy. The cavalry are really cool looking but are also lightly armored despite their special rule of causing a panic check. This makes them more of a 'medium' cavalry suitable to perhaps taking on light troops in the flank and war machine hunting. The Boyars give nice added ability to the unit to make them stubborn but cost more than Captains and don't have as much adaptability.
So, thoughts and questions.
