I agree with this completely. Now, you just use the number of berries you need, and no more, without any crazy re-EVing.
Anyhow, I just got off random free singles. I was nervous because... I was using my newly-raised team of all UU pokes! Hadn't been battle-tested yet at all, and I know random is overflowing with Chomp, Latios, Terrakion and friends. But what do you know, I won all 5 battles in a row.
And guess what else. All disconnects, all right after their last Pokemon falls.
It really pisses me when I beat a 93-win player, using a full team of legends (all shiny and in master balls, hmmmm), with my UU pokes and they D/C. I really don't understand that mentality. No rhyme or reason to any of it either; 3 Americans, a Japanese, and a Brit all D/C'd against my team of Houndoom, Mamoswine, Gastrodon, Lilligant, Gurdurr (NFE FTW), and Gyarados... yeah yeah Gyara's not UU but hey, close enough.
I have to say though, despite the D/Cs, this is the most fun I've ever had on random. There's something thrilling about knowing the odds are stacked against you and still coming out on top (even if it doesn't count)!
