DG vs Dark Angels

It was my first time playing against Dark Angels since 10th edition and I lost again. In fact, I’ve never won a game against The Lion.

I thought DeathShrouds were the best Termies in the game, but that title firmly belongs to Deathwing Terminators. They tore up Mortarion like paper. It wouldn’t have been nearly as bad if not for their -1 damage ability. It was over before The Lion even got involved.

Any advice on playing against DA? Our high toughness feels almost useless against them.
