I only mean the main series game. I mean, in nearly every single game, there are some bad guys trying to destroy the region. In some games, the champions personally help the player in stopping these bad guys such as Cynthia and Lance in platinum and heartgold. But in all of the main series game, the elite four are just 'meh I don't get paid for this crap' throughout the chaos the bad guys are causing. So, my question is, was it ever explained why the elite four is only worth milking for money or xp or is the reasoning for this all up to speculation?
Note, this is not an opinion question. I'm just asking if this is just something gamefreak left for us to speculate or if there was an article or something explaining this one
