Why do pros play on a delayed patch?
Just something that's been swirling around in my head.
Riot has proven in the past that they are more than willing to restart matches over bug occurrences, so that's not a legit reason.
I don't really think practice is a valid argument since much of their practice is on ladder games that are on the most up-to-date patch.
Besides, I don't know about other people, but personally I have a hard time ever watching any game that isn't the exact same from what I've been playing. I especially love when they are thrown a new patch and have to adapt on the fly. When they are on a delayed patch it almost cheapens seeing a pro do anything because I'd already know said move was OP and was going to be nerfed the following patch cycle.
