GW had 2 options when releasing gitmob, first is what we got and they shoved them into gitz, destroying the strong visual and thematical cohesion of moonclan grots, troggoths and spiders.
Adding a new subfaction of cavalry in a army that already had 3 cavalry options in hoppaz,boingrot and spiders.
Second option would have been to put them warclans ,which just kinda would resurrect orcs&goblins ,something GW doesn't want to do even though kruleboyz already bought troggoths and hobgoblins back.
In the end we got the worst result with gitz getting something they dont need and kruleboyz losing a potential cavalry option.
