Wow, Banevv, as far as NJO and DN books go you don't know jack.
You're saying Jacen sucks because he lost to some Yuuzhan Vong when it was what, maybe his third year of Jedi training? The current version is DN Jacen, who can create force shields to protect himself and others from blaster fire and he can make totally life-like illusions of himself that can fool even Jedi. Jacen got really powerful in Traitor and then gained a huge amount of power again during his five years of self exile.
DN Jacen pwns Obi-wan in both force combat and lightsaber combat. Jacen could likely give Dooku a hard time at this point.
