Non-zerg ways to help my server?
Upgrade the things you hold, refresh siege, kill yaks or escort your servers yaks, stomp people when your server has bloodlust, rather than DPS them down, as it adds 1 point for every stomp. Scout, keep the map updated to zergs moving around the map you might see, or find out your servers teamspeak and join in, that way you can hear where zergs are going and help scout. Run supply to places, people who run in zergs will often not stay behind to repair walls/gates etc after attack, so run supply from close camps etc to repair so you don’t drain the supply from the tower/keep for siege etc when it comes under attack again.
Also, when you are running with a zerg, learn how they work, a thief in a zerg, who like you is a glass build, is nothing more than a rally bot for the other server. something you can do is notice where their casters/healers etc are, they are often behind the zerg, or running around the outside, find them and take them out, you can run around the outside without much problem and they are often so focused on spamming 1 at the zerg they never see it coming.
focus on learning how to solo flip camps, tapping those waypointed keeps and getting away alive, and killing yaks and sentries, that will help teach you how to quickly move around the maps while avoiding the zergs who like nothing more than running over solo players
next focus on repairing keeps and building and maintaining siege, so if the call to defend a keep or tower goes out you know just where to go to help wipe those pesky invaders
once you have settled on a build run around the ruins and help your server get those bloodlust buffs, its a great place to find small group fights and the occasional 1v1 fight, but note some servers will send their zerg in if you get too annoying :P
there are a number of very strong WvW theif builds out there I would look at some videos of some small man groups like oPP or RIOT for example who run some solid solo and roaming builds without being too glassy, they have some good information to get you a base build which you can then alter to suit your playstyle
best of luck and have fun
Laundry list of items to do if you don’t want to be in the zerg:
Scout. Perfect for thieves. Keep watching the enemy movements with stealth, or watch key locations like stone must, report things out to map chat. Invaluable for commanders.
Capture supply camps. You can solo supply camps with the right character. This is something every commander needs: dolyaks bringing supplies to their towers and keeps
Hunt Yaks. Enemy commanders hate not having supply.
Capture ruins: can solo too. Bloodlust is nothing to sneeze at.
Capture towers: getting keeps with a small band is tough, but routers with a 3 to 5 man group is easy.
Upgrade your keeps. Thankless job. But someone has to do it. That waypoint in the keep can make the difference in getting reinforcements to your zerg fighting for that last ppt.
