I noticed a couple of grammar things (an extra parenthesis here, capitalization there, missing apostrophe elsewhere), but it is time consuming to point them out for you to fix. It would be nice if I could modify it myself.
Your definition of griefing may be a little understated. Making something more difficult for someone else alone is sometimes required or for the greater good and not griefing. Griefing has more of a malicousness to it and generally doesn’t benefit anyone except for the griefer’s entertainment.
The only thing I see that I think actually needs modifying though, is the question regarding circles and settlements. I think you should clarify that the question is referring to the blue circles on the bottom right corner of the settlement. Further, that makes me realize that I have been asked a couple of times what the gear-like circle around a settlement is and what the different sizes and darkness of that means. So:
What is that gear-like circle encompassing a settlement?
That represents the fortifications of the town. The bigger and darker the circle is, the stronger the fortifications. Fortifications range from +0 (no gear-like circle) to +10 (a highly fortified +6 town with an added +4 fortification ability having been used on it) (the big, dark gear-like circle). Fortifications are strength bonuses applied to every Hero and every unit in an Army. This can give a significant boost to strength if there are a lot of units in the town, enough to hold off strong armies or drastically reduce casualties.
