Yeah, in a case like that, I as leader of my alliance would politely take said member aside and tell him…
“Hey, buddy, we like you, we really do. We understand that you’re very busy with real life stuff, and there’s nothing wrong with that. But you keep missing war hits on a regular basis, and we can’t have that. I think it would be best if you opted out of wars for now, until you’re ready to fully commit to participating in them.”
Then, if he refused… and repeated the same behavior in the next war… well, I’d have no choice but to kick him.
I really hate being put into that position in the first place though, which is why I try to thoroughly vet all of my members before allowing them in.
Should also note that warring is not mandatory in my alliance. Nor is hitting every titan. But those who voluntarily opt into wars are expected to fully participate in wars. We don’t have a draft, all warriors are there of their own volition. The second they clicked that “opt in” box, they agreed to use all 6 war hits to the best of their ability, and for maximum effectiveness, for the purpose of helping the alliance win, not for purposes of personal glory or lazily filling PoV requirements.
