Remakes are broken

So I was in a ranked flex playing with my buddies against another 5 man and we invade their jungle in classic 5 man mode. We killed 3 right away and expected an easy win. They then had one of their buddies disconnect to avoid the whole team receiving a loss and my team receiving a win. All of them were accounted for and didn't leave the match until they knew that they couldn't win. Didn't really know where to post this but the main idea is maybe Riot can lower the time limit that remakes are available or perhaps make it unavailable if all members had already bought items.
