The early safety car introduction from that crash sparked a rush to the pits for the majority of the field, and for the final 30 laps with nearly all on the hard-compound Pirelli, it was a case of management to the line.
Max Verstappen was particularly vulnerable, claiming the final laps at Spa-Francorchamps were a matter of caution given the level of vibration he was experiencing from rapidly degrading tyres.
Horner feels it is time for changes to be made as he said: "I think one-stop races are always boring.
"I think you need to have two-to-three-stop races, I think that mixes the order up, mixes the strategy up.
"I think we have always seen the one-stop races where drivers are driving under the tyre, trying to conserve the tyre, it is very tough. I think that you need some more variability of strategy in order to create offsets between the cars."
Suggested to Horner that more aggressive compound choices might be an asset, he replied: "In an ideal world, I think the most fundamental thing we need to do is increase the number of strategies you can go into a race with.
"Pretty much everyone [in the Belgian GP] elected to take a one-stop strategy there. That's never going to produce an exciting grand prix."
