Let's have a look at the numbers first. About 25-30 Yllses for 15 Zypern.
Now let's look at the final results: After 1h10 of war, Zypern lost and Yllse had only one stone left.
Zypern attack team was composed of 2-3 blasters and one semi-afk priest. 1-2 Vyseus were helping as well.
Yllse defense team was composed of about 15-20 people.
Yllse attack team was composed of about 10 people, including 2 SS using priests.
Yllse had to use a SS thief and priest in order to finally break our last stone...
Which means, Yllse nearly lost a war in which they were playing the lamest way possible and were outnumbering everyone.
I'd really be ashamed if I was Yllse
