You have no boyz.
Ghaz with kommandos is a one-trick pony and not even a very good one. He has
snp so any suprise attack you throw may be ruined if he rolls bad on his
snp rolls. For Ghaz to work, you need need NEED a ride. I can't emphasis this enough. He is also far too many points for this points level. Just stick a regular boss in with 'um, it works fine.
I don't understand big bomms. They arn't very good, and koptas should be suiciding tanks or longfangs or broadsides, not dropping a lousy
str 4 pie plate on some gaurdsmen. Drop 'um.
But them main thing you need to to in this list is
GET SOME BOYZ!!!!!!!
I cannot stress that enough.
