pull up stats for the highlighted part for both Comet and KT pls, because I'm 100% sure the claim is pure BS. And comet is not cheap.
The kt is no doubt better but you can only have one kt since its a heavy-effective vs everything tank but the comet doesn't have a unit cap which is at odds with all the other generalist heavys and at odds with units that have shit loads of utility like jager command squads and officer units, imagine playing vs wehr with 4 jaeger command squads.
It would be annoying since they could operate alone without a spotting unit & negate their natural counter (mgs) and offer so much utility & bang for buck the wehr player wouldn't build anything else, the same is happening with the comet.
Also I dont know if the comet stats take into account the +10 accuracy buff from the commander upgrade in the infantry dps table as well as its high moving accuracy unless that was nerfed.
