If you want to minmax then probably, of the options you put up, ogre or troll SK will give the best results. Realistically if you are new to the server most of your pvp experience will be getting ganked by pkers you stand no chance versus, or slap fighting against other undergeared nooblets. SK is not really a noob friendly class as you need a lot of $s worth of armor and weapons to be truly effective.

The most minmax 1st pvp character (imo and much of this is regurgitating other's posts) is either a halfling druid or human wizard. Both have way better exp bonus/lack of penalty. Your ogre/troll SK is going to take forever to level and both human/halflings have exp bonuses. Druids and Wizards both can pvp reasonably without gear if they pick their targets correctly. Note that magic resist for twinked gankers is insane on this server, so don't expect to ever kill a well geared character, or even defend yourself for that matter... but your SK/Rang/Pall wasn't going to be able to fight a pker anyway. Both druid/wizard can gate and druids sow probably stands the best chance to escape an attack. To boot, wiz/druid can both port which will give much needed $ since the economy on this server is fucked as hell for new characters.
