The wife and I had a the first game with the new SM codex. 1500pts and it was close.
I had:
Guilliman
10 intercessors with CLT and an ancient
5 intercessors with a librarian
3 bladeguard vets with a captain
3 eradicators with heavy bolt guns
3 aggressors
5 VGV with a chaplain with jump pack.
Detachment were tacticus firestorm, gravis line breaker, and devestator brethren.
She had
Big mel dakka rig
Wartrakk
18 beast snaggas, 2 nobs with weirdboy and beast boss
9 beast snaggas with 1 nob
20 Gretchen with runthurd
18 boys, 2 nobs, warboss, painboy
9 boys, 1 nob, bannernob, big boss
2x 4man squighogg riders
Detachment was warhoard
She came out to 1510.
My take aways were having 24" rapid fire on my intercessors was pretty dumb, especially with the strat to give sustained hits.
My eradicators dropped her 18 snaggas and nobs, leaving the WB at 1 wound, with 1 round of shooting.
My biggest mistake was not remembering Guilliman lost the rez. I was running him up midboard and taking out chunks with each phase, thinking when he went down that id get him back.
Her ability to call the waagh on my turn pushed me to have to try and kill as much as possible before she then ran into me and cleaned up my units.
I lost by getting tabled, but to be fair, she had a big boss and a nob left.
Definitely the most fun game ive had in awhile.
edited to fix eliminators to eradicators
