So a recent addition I've seen in pro games lately is how the viewers can see the timers for when the inhibitors return, a filled up bar and a literal timer. It's a very helpful thing to have since you get to see how much more time these teams have until they need to rebreak the inhibitor or to see when they're about to lose a good advantage.
So this got me thinking: Can we players have a in-game timer? It could just be directly above the individual inhibitor and not change anything else like the scoreboard.
We always know they respawn after 5 minutes exactly, but I think it would just be a very convenient think for everyone to have since in a heated game, we're not always, or usually, keep track of when they were destroyed and how much longer we still have super minions.
