So with the impeding updates to space marines in general, let's come up with some cool/good rules changes for our dudes.
Firstly, I like to change grim resolve into +1 BS (including overwatch) within half range or if the unit hadn't moved in it's previous movement phase. additionally, RF plasma gets the benefits of Bolter Discipline if the detachment contains no ravenwing or deathwing units.
I feel like this makes our infantry have better quality shooting and emphasizes taking good ground/positioning. As well as having the added bonus of having a pure "greenwing" detachment.
Secondly, detachments that share the Ravenwing keyword can advance and shoot assault weapons at no penalty, additionally, non- assault weapons become assault "x" when the unit advances. This allows RW units to never not be jinking and shooting, a big complaint.
Thirdly, detachments that share the Deathwing keyword have +1 toughness (might be fun to have t8 contemptors and t9 land raiders) and Deathwing detachments don't suffer the aim penalty for moving and firing heavy weapons.
Other hotfixes include fortress of shields working in both the shooting and fight phases and more broadly, a general +1 attack to all space marines.
What do you guys think and do you have any other suggestions?
