Good tips for those uncertain yet:
Warrior->Trojan->Fire. gives you plenty advantages for pvp. Cyclone makes you hard to hit and enables you to keep locked on anyones tail, even the speedhackers (for aslong as it lasts atleast). But the best part of it is you keep flying moon, even though its just a xp skill it is the strongest magic atk of all. A warrior can do decent dmg with it, but a fire can do immense dmg with it.
Water->Warrior->Trojan. The ultimate trojan solution. Gives you reflect wich helps against fires and archers and might save you from random FB/SS or Herc. You also get WaterElf which will allow you to lvl in TG twice as fast as you would otherwise unless you have NightDevil. As a small bonus you also get stigma for those who wanna spend some points to mana.
Since Im a warrior I`ll either go for solution nr.1 or Warrior->Warrior->trojan, Warrior->Warrior->Warrior or Warrior->Warrior->Water. Time will show which one I go for
Just remember what ol' Jack Burton does when the earth quakes, the poison arrows fall from the sky, and the pillars of Heaven shake. Yeah, Jack Burton just looks that big old storm right in the eye and says, "Give me your best shot. I can take it."
