I agree with "19fishw"'s feedback!
But I think it would be better if the crit multiplier didn't exist for normal zombies, only for specific zombies to take effective damage, like the magma golem zombie and the "slime" zombies from the sewers (which we don't have yet).
The elemental meta makes the game very boring and easy, since you also increased the crit multiplier.
I agree that we should be encouraged to use ice plants in the volcano, acid plants in the sewers, and electric plants in the swamp, but not in this artificial way.
In PvZ2, fire plants heat up other plants, preventing freezing, while zombies cannot be frozen, reducing the efficiency of the iceberg lettuce, for example.
A good example that already exists in the game of what should be done is that in normal lawn, there are levels where lightning strikes, and electric plants are immune to it and gain attack speed bonuses; we can use the umbrella to counter it, or fill the area with electric plants, which will benefit from that.
That being said, I'd like to praise the update; the game has improved A LOT, like, REALLY A LOT, you guys are amazing, PopCap! But there's still room for improvement.
I did a quick translation and there may be errors, but I'll write a very detailed suggestion later about what I think could be changed!
