Sure, but in DIRECT COMBAT accuracy and RA are still undeniably preferable. The healing and vision are certainly good, they're just not combat stats.
But it's part of a big picture. Always having full health while not a direct combat Stat, directly impacts combat.
It doesn't matter how good the RA is if the first shot from an enemy is going to drop a model and lower dps.
I even think that moving the healing back to vet 3 would be enough to really help okws mid game and scaling, helping maintain pressure and get over the healing hump if they go mech.
