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.
If you see such anomaly like the Luch's damage graph (with a pretty big spike in the middle range), it's pretty safe to report it here, since it's more likely than not, that it's just some error on the site.
In this case, I'm sorry to say but it's again fault of Relic's inconsistency - it will have to wait until after Christmas for me to fix it though.
Those values are not necessarily correct, they're calculated against vehicles and may not (I am unsure) take spread into account. The T-70 does 40 damage a hit and is very accurate when still, it generally kills a model every 2-4 shots when not moving. Against a Luchs the T-70 will win unless you're facing your rear armour to him.
Graphs on my site don't take into account any AoE damage or scatter.
Saying that, it has to be noted, that T-70 has it's near (so full damage) AoE over 6 times as big as Luchs.
