If i where you
id replace the defiler with 2 more obliterators or at least throw the third obliterater with the other 2
My defiler dies when he assults and misses when he shoots and its a lot easier to kill a lone obliterator and a 2 man squaqd then 3 toegther
I'd either give the berzerkers a rhino or use the other 2 rhinos to block the berzerkers from enemy
los
I'd also invest 5 points for each squad to give them personal icons so the terminators can deep strike within 6 inches of them w/o devieating(sorry for spelling)
The
hqs look great it might help to give the daemon prince some wings so he can get closer to the enemy faster
Well
gl with your chaos army
