I agree that assault engineers are pretty handily better than sturms, but if we were to remove the .91 target size and move it to vet1 IMO reinforce cost should go down (maybe 28-29) too. That way they're less overly combat efficient but they also bleed a bit less too.
Thats exactly what I was thinking too. Without the .9 RA, theyre not really worth 30 MP per model. Theyre currently better than sturms overall as a squad, but slightly worse than them model per model. If they become even worse than sturms model per model, their reinforce should probably reflect that.
