Annexing missions = diploannex only in HTTT?

[Darkrenown]

It's intended. The missions give +1 centralisation to counteract the -1 from diploannexing. You don't get to dow them for free centralisation, I'm afraid.

Since you have cores on them you can DoW stab free with the reconquest CB if you want to annex them by force though.

I suppose you could do that to save time, but FRA has missions for all or almost all their vassals that grant centralisation for annexing them to counter the diploannex anyway, that's the point of them.
