Other Classes: Class for solo PvP'r/casual WoE

As stated in the title, I'm mostly a solo player.
I'd like to have fun in PvP rooms and participate casually in WoEs (wich means I won't attend 100% of WoEs nor make a build 100% for it).

Right now I have a 5x Swordsman I'm leveling so I tought of one of these:

- Vit based Lord Knight (97 vit, high STR) with Bowling Bash and Pierce
- VIT>INT>DEX Paladin with Grand Cross, Gloria Domini, Martyr's Reckoning
- VIT>STR>DEX Paladin with Rapid Smiting, Gloria Domini, Martyr's Reckoning

Wich of these 3 would best compliment what I want to achieve?

Or should I try another class entirely for solo PvP?

Thanks in advance :)
