The requirements for legendary weapons have been discussed since release. Since gift of battle is still necessary, some tips from a pve player who also needs to play wvw from time to time:
- If the maps are completely empty, you are probably playing in a time away from the peak time of your server. Try another daytime. Each server has different peak times during the day.
- If maps are still empty, your server is probably in a bad link. In this case, the better solution is to wait until the next link reset.
- You still can solo doing small objectives: camps, doyaks, veterans, etc. Try using a roaming build (check metabattle). If an enemy roamer (thief, engineer, etc.) is camping, ignore him and go somewhere else (or another map).
- Remember: you only need to stay on level 3 participation or above. It means after capping a camp, tower or killing an enemy, you can sit at some safe place and wait about 10 min still earning credits toward the reward track. If you really don´t like wvw, go to youtube, netflix, etc. in meantime (just don't do it on queued map so not disturb other players).
