I lead a war a month back. Teams were

US:
117 MS
137 EK
94 RP <- my char, friend on it
255 MS <- me

THEM:
262 EK
190 MS
150 ED
140 ED
140 MS
105 ED
105 MS

Needless to say, we won 6-3. One of their frags was on my 94 RP. The other two were with the help of a 270 MS, 245 EK, 100 ED and some others (like 5 people total?) on my 256 and my friend on his 137. I also led some teams you can see videos of on my youtube channel, but I've never gone full-scale war on real Tibia, only OT's.
