i don't think so, i don't know your server situation but for example my enemy clan use multiaccounts against my clan
and nobody wants more zones due the multiaccount problem
Multi accounts is a problem that shouldve been solved and must not be part of the game, it can be used for defense too. If there is only 1 person in 4 accs and taking gates it does not mean attacking is easy, its cheating. We have to see it with actual players. And i believe it is a fact taking over a gate can be very slow, you should know it beforehand with the amount of gates clans hold in your server xD the only different thing is that other clans dont interrupt, while what you should see is an ally clan stealing the buff from the drainers.
as i said clans are neutral, others are in clan vs clan war for the map. For example i had zones in ccv but the clan there didn't helped me to defend and neither to my enemy, same at gv (well until the enemy decided to attack both of them), and nobody is helping the current war at goldfields
I dont believe clans staying neutral against other enemy attacks is bad, but its not good for the game having too many clans holding gates either. In your situation, years ago, this big neutrality wouldve never happened because there was a competence for sheriff, rex etc but its obviously lacking now and the system encourages to have many clans in an alliance or in this case just holding the gates
