2H melee specialist Options

[rbeverjr]

Great players of IA who can rule the game on insane with ease, please let me know which melee person you consider best to wield 2H weapons (particularly halberds) and why. My thinking is kensai or barbarian. The kensai should be able to Greater Whirlwind and hit just about anything but his defense will suck without potions or Spirit Armor. The barbarian has much better defense (rage, resistance, good armor), but he may be using Critical Strike rather than Greater Whirlwind - not sure which would be optimal. But these are the thoughts of a lesser player. What do you think?

@ bulian What I actually mean is the D-> F, not F-> D...I tried the Shapeshifter(13)/Fighter, and additionally installed the “Shapeshifter rebalancing” component of cdtweaks. I found this class interesting, with a higher damage output, though not as comprehensive as the avenger and FD multiclass.
As for F->D, I personally think this class is pretty weak, nothing special.

Indeed, it's a bit too long for the assassin23/Fighter to take shape. I recently designed a party of multiple rogues, including an Assassin 23/Fighter, hoping to win several key campaigns with backstabbing. But after playing for a while, I gave up and changed the A23/F to a K9/T... If someone wants to experience extreme backstab damage can try this class, otherwise the Kensai/Thief can take the place .
