Except what he said was empirically false.
The luchs has a peak dps of 28 and a low of 17
T70 peak dps is 17 with a low of 8.8.
Not to mention that the luchs' peak comes at mid range, whereas the t70's is melee range.
This, combined with the fact that the luchs can take one more shot from an AT gun, shows that there is a slight imba in favor of the luchs when compared to other light tanks.
Numbers don't bullshit, people do.
And people also forget all attributes. For example a T70 AOE near is 1.25 vs a Luchs at .5 So for all intents it's DPS will double with squads with more than on entity and blobs. That's not a small improvement over the luchs that more or less guarantees full damage to two entities at once.
