Quoted from GP...
For people with enough candy to power up a Blissey with a suboptimal moveset, just power her up and stop being such a perfectionist. Blissey with any moveset is much better than the best Snorlax.
I have a Blissey of the same moveset but poorer IV=71%. I maxed her out and enjoy throwing her into the gym. None knows when Blissey will be nerfed.
Live for now.
