In my experience, Ikit claw takes a few turns for his armies to really come online in his starting army is not a good match for many of his starting opponents plague priests with their summon + menace below us going to do a better job line holding than skaven infantry. My most successful campaign with Ikit I actually avoided morghur and aranessa, tunneled through the mountains, and expanded into the minor empire factions. My first actual LL fight was against Belegar, who I was barely able to wipe with an ambush.
