You're right, I'd probably do better in a competitive MP game, more incentive.
I'd use mercs and expand faster, wider. I'd blitz the weakest bastard who'd border me and double my nation in almost no time, with very little loses probably.
That is if everyone didn't decide to gang up on me from the start. But why should they since Ashdod is ruined now?

I have no doubt a gang would kill me instantly in the first 15-20ish turns of course, but, if I were left to kill my first neighbor which would have no chance in hell what so ever to fend off from this, even a 3-4 side gank would have trouble putting me down at that point.

Any nation that is unstoppable in a no diplo game should perhaps get some changes. I count Ashdod as such a nation personally. Not because of the mages, sacreds, summons, good national troops, but the absurdity that Adons can become very early on. And as such I don't think they can be balanced at all, nor Ashdod for that matter.
And this is why it will continue to be ganked upon always, whatever nerfs are implemented.
