I recently had a match against the Celts at 1,1k elo.
They went for a Drush that they got lucky with and managed to idle my Forager Villagers and deny my Barracks.
I decided to counter with a Scout Rush and was able to get some Villager kills and had a 6 Villager lead.
However, my opponent reached Castle Age a minute before me and built a Monastery and Siege Workshop next to my base, which proved to be devastating.
They didn’t create any additional Villagers and just completely focused on pushing me.
I had lots of resources but I couldn’t keep up with their Knights and Monks raiding and protecting their Siege.
In the end, I couldn’t save my Villagers, keep up the production and save my Town Center.
