You mostly have to depend on your personal skills, your knowledge how to play HtH.
Practice, you have to be fast and have a good mouse to pvp players on battleground

And dying is normal. The thing there is that you don't loose anything, you can quickly doc + fa yourself after respawning and go back to the city you were fighting in. Now it should be even easier when you spawn near the place you died.
Personally i had fun fighting snipers. When you encounter one, hide near a building corner so he can't shot you. Now get as close as possible using the obstacles that don't let him shot you, and you can go out when you are ready. Now hit him 1-3 times in his hands(thats the maximal you can do with 9 AP) and make him drop his weapon. If you aren't lucky enough, try to hide again. The weapon should be dropped in most cases since you have Better Criticals and 70% crit chance for arms, and if it is, pick it up. Now eyepunch him to ko/kd/instakill. You can try attacking his legs to cripple, but i don't think it's very effective.
You have to know when to retreat. In a middle of a hard fight you can FA + Doc yourself and continue as well as a fresh respawned player

Keep practicing.
