>>50183148Because it doesn't fit as a grass starter.
Its color scheme doesn’t have enough green and it doesn't have any distinctly grass characteristics : Venusaur and meganium have their flowers, Sceptile has its fern-like tail, Torterra has a whole tree and Serperior has a few leaves on its second skin/coat. Chestnaught's barbs give it more of a porcupine look than the chestnut its supposed to look like.
You can see how Chestnaught doesn't fit with the rest of the grass starter when they are put next to each other.
Also Grass/fighting is a shit typing for a pokemon supposed to be a tank, I'm pretty sure Chestnaught would have been liked more if it was part steel.
