Pelago is fucking incredible, fuck the impatient retards who shit on it.
I also work 6 or 7 days a week with classes, and it is a life saver. I'll have a few hours when i get home from work, and i'll just tauros around and send a box of eggs to the PC, put 18 of them in the spa, and hatch them during my lunch break the next day.
Sure island evelup can be slow, but it trains 18 fucking pokemon at once. Even if it takes 40 days to get to 100, divide that by 18 and it's probably not that much more that you'd have to manually take 6 pokemon through the elite 4. It's also nice to let pokemon automatically get EV trained over night.
