If the dealbreakers wanted to war SWEA then they should have waved SWEA since *they* are the ones who want the war. If you want to war someone and they do not to war you on your terms, then you need to force the war on them by hitting them.
From how they handle themselves all age they do not seem very bright: if you know someone is going to wave you OOW and you want to fight someone else then you need to be able to wave your opponent of choice before you get waved, this can be done by exiting eow/fort earlier and making your wave.
The argument of hitting someone into war just because they made you waste resources pumping is not a good one. No one is even guaranteed a cf so they could pump, how many ages did some kd deny some other kingdom cfs to pump science or even cfs to grow into range? Happens all the time. How often do these top kingdoms double team each other? Never unless they are baka.
In this case though mansoor made a pro move because debauch has a **** rep, just dealbroke two kingdoms, and offered them a CF to be reasonable with them or asked them to give button if they wanted war...having this set of circumstances lets swea hit into war with impunity as no one will care what happens to these guys. The actions are not clean as its not justifiable by community standards to double team someone because they made you pump but ****playing against dealbreakers who **** play others and are likely to ****play you as well is perfectly fine. For a better PR spin I'd just have said "they dealbroke two kingdoms, they might dealbreak me next so **** them"
I honestly don't see why these guys didn't just want to keep their deals this age and play fair, especially if they wanted to prove they were good at warring, when you only get WW due to dealbreak you get no credit and others just ****play you back and you lose everything you gain...seems like a waste of time.
