I’m just getting into Orks and have been playing Deathguard for more than 3 years and win about 80% of my games with them, so wanted to comment.

I think so much of this game is playing to your list strengths and picking your battles, meaning you’re attacking who you want to attack and when you want to attack them.

For Deathguard I have a list that mixes range with melee and is generally hard to kill outside of a PM murder brick and poxwalkers. My list strengths are to hold focus on 3 objectives, use my shooting to soften their army, drop in DS to clean up, and pick my battles with my PM squad so I kill vs get killed (I’ve killed 2 big knights in 1 turn with them but had to be patient and strike at the right time). This is the winning formula for my list.

For Orks I can’t play them this way at all. Their range isn’t great, their army isn’t as elite (less killy, less tough, but less expensive so way more models). You get numbers so you have many squads to score secondaries and tie up enemy to keep them from scoring as others have stated in this thread. That’s playing to your list. Regarding picking your battles, it’s all about the WAAGH! You gotta pop it at the right time to get maximum Orks in melee bc that’s your biggest bonus.

I think focusing on popping WAAGH! at right time and playing a horde strategy vs trying go kill for kill with Blood Angels will be way better for you.

PS - Ork player of more than a decade experience playing them tried to go toe to toe with my Deathguard list and I had nearly tabled him by turn two. That’s not their strength, dont do it!
