I understand why you feel that way, but Exploud is a wallbreaker after all, it's meant to have zero switches sure you can argue that clicking a single move lacks skill and is cheap (which isn't true at all since some things in the tier can tank Specs Boomburst such as AV Escavalier, Registeel and your Rhyperior) but a lot of other wallbreakers do the same in the tier, here is an example of one of the fastes and strongest wallbreakers in the tier and my personal favorite:
Yanmega @ Choice Specs
Ability: Tinted Lens
EVs: 4 Def / 252 SAtk / 252 Spd
Modest Nature
- Bug Buzz
- Air Slash
- U-turn
- Sleep talk / Shadow Ball
Screw Exploud this is THE wallbreaker of the tier with Choice Specs and Tinted Lens Yanmega can destroy anything that doesn't x4 resist Bug Buzz and unlike Exploud it can't be revenge killed easily thanks to a solid base speed stat and with hazards suppor (especially SR and Sw) Yanmega will perform a lot better. U-turn is there for momentum and the last moveslot depends on what your team needs: if a sleep absorber is needed Sleep talk is the better option and if you need to hit Doublade use Shadow Ball.
Some fun calcs:
