-everytime I use Mudkip, I always keep it a Marshtomp. - Competitively I always use Quagsire, Whiscash, Gastrodon, and eviolite Marshtomp over Swampert as I will never use it. If I have to use one I let it faint. (I hate the Tympole line even more so make sure to never use it outside pokedex) -to complete the pokedex I ALWAYS trade for a Swampert and trade back or release -If Swampertite exists, I will ALWAYS toss it -Sceptile and Blaziken lines are far much better designs -In RSE when I pick Mudkip, it becomes an HM slave and replace it with Walrein, Wailord, or Milotic. Only twice have I picked Mudkip as the many playthroughs always go with Torchic/Treecko (if you're wondering, I never found Feebas in any Mudkip playthrough)
If Delphox gets this horrible treatment, then I should treat Swampert exactly the same.
I honestly don't like Swampert either, but just because Delphox is getting flak right now doesn't mean you should do this too.
Here's the thing. This is actually natural that people do this. Every generation is same old cycle. If and when there would be a generation 7, some Pokémon will picked on because of looks, if it's based on an inanimate object, or what have you. This whole thing is nothing new. So, I don't think making fun of Swampert is going to help the issue.
