I am not saying that is broken or op, i am saying its plain boring and unfun
Dok was tier S for a period and morathi was not the reason but surelly part of it, she can block whole armyes alone and hits like a truck
Gotrek is totally a different matter, hes slow like hell and does nothing other than being a beatstick
You cant ignore a flying teleporting monster that can charge everywhere and cant be killed in 2 round at best, and makes a unit shoot 2 times (and with DT this rules is broken as hell)
