[House Rules] Immobilizing AT Fire

[Hugmenot]

I always ask myself a few questions when thinking about adopting a house rule.

Is the house rule difficult to implement?
No, it's very easy to implement.

Does the house adds significant playing time to a scenario?
No, I doubt it adds more than 5 -10 minutes playing time to large scenarios with 150+ units.

Is the house rule unrealistic
I lean towards no; immobilization with later recovery without loss of firepower did happen.

Is the house rule unbalanced
It depends on the scenario on my opinion. An attacker which has many more AFV's than the defender may be negatively affected by this house rule. Not only an AFV may have to spend a few turns recovering morale, the attacker may need an activation just to attempt that recovery. If playing a huge scenario (say 200+ counters) with the optional fog of war rule, the net effect of the immobilization may be too punitive for the attacker.

I do like the chrome at little cost it brings and thus I will probably try it in a small to medium scenarios t before I decide whether I want to try it for larger scenarios.
