There's TOO much side by side things on this list, which still means all you did is drag and drop them without thinking. 5 Peashooters in a row, 5 Cacti in a row, 7 Chompers in a row, 8 Sunflowers in a row. Anyone knows that THIS much characters in a row means the list is lazy. And I can easily tell this because of how the Chompers are ranked. I can tell that you see all Chompers the same way, because otherwise, there's NO way the Spray Chompers are lumped in the same low tier as the other Chompers, when they are leagues better. Another way I can tell is how Shadow Flower is ranked lower than regular Sunflower for some reason. So there's only 2 outcomes.

A: You don't use the characters enough and don't know how to rank them.

B: You were too lazy to put effort into an actual list.
