Well, I saw the moveset for Slaking, and it said "Hyper Beam can be useful only in a handful of circumstances. I don't see why it is better than Return, since it has Traunt. Anyway explanation please?
I assume you meant to say "I don't see why it isn't better," otherwise your whole post doesn't make sense. The reason is because Return will let you switch out and Hyper Beam will leave Slaking in there, useless until the next turn which will let a whole host of sweepers setup on you.I don't see why it is better than Return, since it has Traunt.
