No point to play on an older patch. The run won't be eligible if it can't be replicated on the latest patch.

They nerfed Zeratul's blink, making Freezard's echoes of the future run unrepeatable.

They used to patch co-op a lot, which makes the runs non-eligible. I don't know how often they patch co-op nowadays.

Woobly that is not correct. LOTV time is not the same rate as normal time. WOL, HOTS and LOTV all have the same time rate.
