Sabotaging a radar

If a scout sabotages a radar, the radar shouldnt just research at half speed, it should also allow the scout to give his team more information. I am thinking about what is currently researching and how many res the enemy has.

Pros:
Makes sabotaging more important. Actually VERY important and useful.

Cons:
I dont know any.

Alternatives:
Sabotaging doesnt do damage to the radar and/or doesnt slow down the research.

A sabotaged radar shows every 30 secs where enemy vehicles are.

 

This was already shot down because of the terrible impact on the balance even if it would slow down research by 10%.
