Logistical effort? That would be like 4 people out of 25 only, there is absolutely no extra effort for any raiders without an officer position.
And even then, I used to coordinate 5 people when I was melee officer, now I coordinate 10 as raid leader of a 10 man, pretty sure I do a lot more work than many role officers, why would they be more rewarded than me?
See, there is no win there. For me the only way to fix 25 man would be to allow cross-realm raiding, but only in that format. Because it's recruitment that is the issue, nothing else.
