Pvz3 needs leveling up

So I played plants vs zombies one but also two, I favor 2 more because you can level up plants and so it doesn't get too overwhelming for the player because for me pvz 1 had one level I got stuck on my dad xbox 360 so I called my cousin to help me later though we got stuck on a fog level I did enjoy pvz1 alot don't get me wrong but I just don't like the fact that sometimes you need to keep choosing different combinations of plants I enjoyed that but my favorite thing about one is actually that if you put a chomper behind another chomper the one behind would take the front seat if the front on was eating but it kinda did not work on the fog level because you would need light but I bet I am upsetting og fans if they see this but I prefer the leveling system from pvz2 because it makes it so that certain plants can help with thing more but their weaker stats go up less the the stats that plant is made for so simply please add a leveling system for players that like grinding and please also make it so you can choose to level up that plant
