Specialist/Gadget/Weapon/Vehicle tweaks and Tier 1 goals

What would you think about the idea of adjusting the goals of the Tier 1 progress on Specialist/Gadget/Weapon/Vehicles that get weakened one way or another since the goals no longer correspond to the performance that the asset used to have?

So lets use as an example the Spotting sensor grenade which got at Tier 1 before it got nerfed. It needs several thousands of spots/assists.

Now after I got the tier 1 , it can only be thrown once and has half the duration. This means that someone now has a lot harder time to reach tier 1 than I had.

Would it not be more fair for those who come after to get an adjustment to the tier goal that is proportionate to how much something was weakened?
