I agree with Sunflower/Sun-shroom, and Chomper.

To be utterly honest, I think that if Citron worked the way you suggest, it would be OP. It has a higher dps Gatling Pea for only 350 sun, and its weakness is meant to be the lack of crowd control. If it were to pierce through zombies until it reaches a damage cap, that would make it lose the weakness, and it would have to cost at least 400 sun to be balanced.

I don't think Citron is outclassed by other plants anyway, the problem is that the crowds of zombies are so big in PvZ2, due to the increased sun value, that most non-AoE plants are near-useless.
