Someone can make a set of rules for what is/isn't legit but until that's done you can't assume everyone has the same assumptions.
I agree, but hope you can see my point in that this discussion should not even happen in the first place.
How is it possible to have a mechanic in game for over 4 patches that's so obviously messed up, screwed up beyond the point of repair, that you aren't brushing me aside with an insult when I call _the main mechanic accompanying a DLC_ an exploit?
Remember how they broke the AI to the point where I was able to place enemy units in provinces the way I wanted to the point where it felt like I had gone beyond console cheats and just activated godmode?
Took them three patches to get it into decent shape. Nowadays the AI is appropriate. Functional.
But tributaries?
Four patches and nothing.
No statement, no discussion, nobody gives a damn.
There aren't even any useful bug reports anymore.
We've given up, simple as that.
End of rant. Felt good to vent. Screw Mandate of Heaven.
