I mean... the primary reason, in my eyes, that most alliances have Do Not Raid (DNR) policies is to avoid unnecessary escalations outside of when an alliance decides to formally declare war for whatever casus belli(s) they desire. Furthermore, it prevents the game, at least for these top alliances, from devolving into being primarily about war rather than involving politics as well.
However, I do agree that NAPs are mostly bad for the game and this one was especially weird with the sub-c10 rule (in my opinion). Furthermore, I tend to like when alliances come to agreements about what types of raids are and are not allowed between their members as well as the terms of such agreements. For example, when I was MA and FA for Aurora, I had seen deals made where an overly inactive member could be raided so long as anything looted from the bank was returned and deals where we mutually agreed to allow applicant raiding under certain conditions.
TL;DR: I like rules (DNR) and believe they have a specific purpose, but enjoy seeing alliances make raiding deals.
