ALLIANCE ANNOUNCEMENTS

You're mixing up the concepts of war and duel – a duel is a competition, like a sport, but war – at least for our clan – is a way to defend ourselves, to defend the clan, if another clan insults us. In simple duels, we will fight for ourselves.

Well, I'm saying "Duel" – if that's the right word... war in my plan is a full-scale entity... (i.e., across all versions of Heroes)... but if it's just one version, then it's a duel... I think these two words have different meanings.
P.S.

This is a way to stand up for yourself,

you can stand up for yourself even in a simple fight... but in war, there's always a goal – to win and get some kind of profit from it – but since we don't have any "profit" (so to speak), I don't think it's right to call the disagreements that arise a war... ;)
