Drake spawn every 6 min will get the game slower
If drakes actually spawns every 6 min with first spawn at 5 again, we would have much healthier league, comeback should be real more often, snowball will be tuned down a little bit and not every game an actual late game at 20th min. Not even mention how much easier it would be to outscale cheesy early picks that never falls off due to endless buffs they have every 5 minutes.
Think about that, this may even bring tanks again. But as I know riot I wouldn't be very surprised if they actually change drakes' cooldown to 4 minutes respawn.
