War victory / Trophy questions

- Really no single aerial unit to destroy ?

- 10 settlers to kill : this one is a bit weird, it requires either a friend willing to make them just for that, or exploiting newbies... Or attacking while someone making settlers is sleeping, either being very lucky to attack while one is entering shelter or destroying the shelter, which also require luck since it can't be directly target. Even so, the future system that makes alliances able to move other members army prevent this way.

- Might it work next alpha ?

I have this building in every town of my heros. I am finding different trophies in each one. Is this intended? I built the trophy hall after Bers posted on forum that it was needed to get the trophies. I just did not expect the trophies to be different per town, in the same hero.

I was curious about this too.  So does it mean that to get any of the war victories, you have to achieve them on a per town basis, or is a per hero basis, or per account? 

I also noticed that different trophies get unlocked the more you upgrade the hall.  If you have achieved something, let's say, one is to kill an enemy hero, (i think gets locked after level 2 or 3)...if you have only a level 1 hall, does this mean you won't earn that trophy until you level up your hall - and if so, do you have to kill another hero in order to get it?

Are there any trophies for non-leadership? Or is the building just for leadership heroes?
