Yeah but it'll hit the cover instead of the squad. Same as every other tank though, that was just in response to the comment that the panther's dps is halved against inf in cover.
EDIT: Are you sure your stats are up to date? Because I'm looking at coh2db and the only thing I see in the comet's favor is that it does more far and mid AoE damage. If I'm reading it right, the comet seems to have more scatter and inferior AoE distances across the board. The comet's reload is also ~2 seconds slower and doesn't get any vet bonuses for firerate.
not all cover bounce, and i get the stats from coh2db too
it says 6.3 aoe on p4 and 6.7 on comet
