Have you bought oracles recently? It has had a time limit of 5 minutes for quite some time now. Now that time limit just keeps on ticking if you die. This way you are guaranteed the full 5 minutes, it's just that you might be dead for a decent chunk of that time.
I'm not so sure that I like the change to be honest. You could decide to chase down the support with an oracles instead of going after another champion in order to destroy the oracles and limit their vision. Expect to see ward clearing becoming more prevalent again as every jungler in the pro scene picks up an oracles early-mid game.
