How do wvw objectives work?
A supply camp that is not upgraded has x/100 supply. Fully upgraded it will have x/250 supply. You can’t determine if an enemy camp has the +5 buff, but your camps will show a cog like boon in your boon bar.
Mercenaries (dredge, froggies, ogres) will display the color of the allies in their lattice thing on your map. When that lattice is white that camp can be flipped to your side and you’ll have mercenary guards in your nearest supply camp.
The middle objectives? Ruins maybe? If your server owns and holds at least 3 of them at the same time, for 2 minutes all players on your server receive a bonus stats.
Where to drop siege is a long complicated topic because every tower and keep is different.
