That is true about focus sight but not for tracking. Tracking comes with no penalties.
The problem comes form the fact that abilities stack and the unit has mini map information on top of that for the duration. A Su-85 with both abilities can see further than most (if not all) stock reckon vehicles. There is nothing to justify that.
Tracking reveals inf on the minimap not tanks. That is not as benificial for a pure AT unit.
The combination of these abilities still leaves the su85 with nerfed speed stuck in it for a few seconds and vision is still in a cone.
If you use tracking without spotting then it is free of penalties. But then it does not see further then stock recon units i wager.
Other td's have either rof, hp, armour, camo, skill shot, turret, actual ai, speed or a combination over the su85. Its one and only signature feature over other td's is spotting and imo that is the justification and has to stay. Standardizing is not the solution to everything.
If the su85 gets something else then tracking or some pop or vet adjustments i am fine with that.
