Build for my chars

Tpvp is sth i wanna get into. I dont just wanna play guard but maybe on some other chars aswell. So anyone who has some nice Tpvp builds for the following classes, much obliged.

-Ranger: probably sb and sword/warhorn or sth like that
- Mesmer
- Thief: Sth for a roamer
- Maybe necro, have a lvl 2 and not to sure if im gonna use him for tpvp

I found a tanky retaliation guardian fun. Make symbols larger with trait, make them do damage and heal you, use AH, GS, get that crit chance and crit damage up. Not much need for toughness, just go full berserker for the HP, power and critting. It's nice in 1v1 (against the spvp players I used it) and even ranged players keep getting damage from you since you have literally 90% of the time retaliation on.
Never tried another class, I do know about ranger, but you got a solid build there already. Was willing to continue working on my own but the weather is to sunny to be inside the house.
