Yeah, it's usually too much effort for me, especially if I'm just casually playing through a file, but I had some friends who played competitively at the time, (using almost exclusivity legendary pokes at that) and there is always something satisfying about taking down Mewtwos, Deoxys, Arceus and whatnot with a humble Breloom, and perhaps a Crobat for backup. (Or, on one very fun occasion, a freshly hatched Starly with F.E.A.R. You should have seen the look on my friend's face.
)
It is a little disappointing, but I've considered over the years attempting to train Olive the Second. Meh, too much effort.
