Tried out the warrior vocation last night. Man, is it slow. But powerful. They don't get a secondary weapon, so they miss out on three skill slots. It was fun smashing dudes 20 feet in the air with my warhammer, but I think I still like fighter more.
Regarding the potential of a port, I think it's a safe bet Crapcom waits to see how Dark Souls does financially.
Holding R2 (as a fighter or warrior or mystic knight) will lock down the enemy so your pawns can stab them in the face.
If this is true, and you can't double jump with swords/shield I might abandon my plans on being an assassin and just stick with the fighter. I generally hate dual-wielding so daggers are unappealing to me. I'll at least give it a shot, but it seems that every other melee vocation has a huge con besides fighter:
Warrior - Slow as fuck, only three skill slots
Mystic Knight - The shield animations taking your shield from your back to your arm every three seconds would drive me crazy
Assassin - Poor defense/HP gains, can't double jump with sword, can't grapple, can't throw dudes off cliffs, lighter armor
Strider - Thinks he's playing Shadow of the Colossus
Fighter seems like the vocation for me so far, which is funny because it's one of the basic ones you can start the game as. The advanced and hybrid classes are more like sidegrades than upgrades.
Fighter - Good armor, shield, lightning fast sword attacks, good melee stat gains, a true BRO that isn't afraid to put a goblin in a headlock and throw him off a cliff
Why did they even include other classes?
EDIT: After testing it out, Assassins (at least with sword and shield) can also restrain smaller enemies. Seems Assassins with sword + shield are like more offensive oriented fighters. Some of the skills are different. Must investigate further...
