I love Slowbro. Unlike you, I have both a Blissey and a Snorlax (only 1 of each), and also unlike you, I don't have a Slowbro good enough for me to invest in. I have some Confusion ones barely over 82%, but as every CP point matters for such a low CP mon, I don't want to max one before I get one with 96%+.
If I had one maxed I would definitely have used it a lot, though. For the same reasons I loved the old Bubble Poliwrath.
