Some guides for roaming builds which should be suitable for Fog's militia WvW events:
Note the recommendations for consumables (Fried Oyster Sandwich and Potion of Karka Toughness), armor, runes, and trinkets. The author recently posted that Durability runes are still the best in slot even after the changes to runes.
For anyone playing condition based classes, consider this food: https://wiki.guildwars2.com/wiki/Oysters_with_Spicy_Sauce
A bit outdated due to some recent changes to traits, but still a good guide for learning the basics. Scholar runes are currently selling for 8 gold each on the TP. A cheaper alternative is https://wiki.guildwars2.com/wiki/Superior_Rune_of_Infiltration.
This double axe build is now meta in PvP (used by Eurantien and Rom) so it will be interesting to see if it catches on in WvW roaming. Sawda, you may want to considering testing this build out. The Siamoth is used for the Plasma bundle that drops from the Siamoth's Foraging skill. Plasma gives all boons when picked up.
