Maybe everybody in Ic is fighting for themselves/their own tel var gain and not for the score of their faction to win the campaign, but that doesnt mean that fights in IC are equal. Althought tel var is split between all group members and other players in the fight and you can kill almost all NPCs in IC solo, people still run around in huge zergs and hunt solo players but avoid other zergs. Almost every fight i see in IC is a Xv1gank. If you dont play solo, you have to share your telvar and probably still get zerged, so farmers play solo and good „gankers“ too, but zergs are zerging down solo players despite getting less telvar.

No. 3 way fights are always the most fun and it's called the Three Banners War for a reason.
