Payload race machanism

There are 3 checkpoints. The cart will pause for a period of time before moving again.

The first team that reaches the checkpoint will go through the full length of pause time, whilst the second team only need to wait half the time.

For example, in Thames district, Checkpoing A is 12s and 6s, B is 10s and 5s, C is 5s and 2.5s.

It doesn't measure the actual difference between the 2 carts. As long as a team reache a checkpoint second, they benefit from the less wait-time.

It is Blizzard's attempt to create "close games" but I think its absolutely ridiculous. non of the fights matters other than the last one.
