One thing that's always kind of annoyed me is how little screentime Elite Four members have gotten in the games, even compared to Gym Leaders. With a few exceptions, they're almost never seen outside of their rooms, and they never have any interaction with the protagonist outside of the standard boss battle. The PWT may have been the ultimate worst example of this, with its deliberate exclusion of Elite Four members with the lamest excuse ever. (If the Elite Four members really were "too busy," then why weren't Lorelei and Agatha, at least, there? They weren't Elite Four members anymore by the time of B2W2.)
The anime makes things even worse with it's ignoring of the normal Leagues of the games in favor of Tournaments, which means that Elite Four members barely exist in the anime. To this day, the Gen 1 group are still the only Elite Four who have all had full episode appearances, and none of those appearances involved Ash battling them in succession to become Champion.
Do you think Elite Four members have drawn the short straw in terms of characterization? I admit that some of my all-time favorite Pokémon characters--Lorelei, Lance, and Karen--are Elite Four members, and while Lance, at least, got off better than most (mainly because of his promotion to Champion), the two ladies haven't been so lucky. Poor Lorelei is still rotting away in the pre-DS era and is unlikely to ever appear in another game that isn't a Gen 1 re-remake, while poor Karen is unlikely to ever get an anime counterpart, didn't get even the slightest bit of fleshing-out in HGSS (like Lorelei did in FRLG), and will probably also not appear in the games again unless there's a re-remake. How sad.
