And this is also where other vehicles fall short despite being similar: The Luchs is very good AI value for its timing, but the ability to camo is questionable and it has not much to scale to the late game: No recon, no other ability.
I do think the Luchs has a vastly superior damage profile compared to the T-70 in terms of balance. The Luchs has enough firepower to force off any squad, it has the ability to chase down and wipe badly mispositioned squads, and it can deal devastating damage point-blank creating an interesting risk-reward mechanic, but it does not have enough DPM to wipe units left and right like the T-70 regularly does and it's worse against retreating squads because it uses accuracy over AOE.
So although the T-70 has better scalability, I do consider the Luchs to be a much more balanced vehicle regarding combat power. Fighting against the Luchs always feels fair, while fighting against the T-70 usually doesn't.
