looks cool bro !!
i think at the end of the day every 'real' GK army will end up being shooty considering all GK has strombolters and psycannons.
if i had 1 thing to comment, its the fortification. fluffwise they are more like a scalpel rather than a hammer or anvil. considering no one ever dares to assault Titan, it's just heresy for GK to sit back, because at the end of the day, even if GK losses, they will just exterminatus the planet wooooot.
like what 'normal marines' would say, welcome to the brotherhood of douche !!
revel in it my brotha !!
