Joel,
It really depends on how you like to fight. I would assume this is for your Ogre?
My personal experience as a fighter is it's depending on a handful of situations (in no particular order):
1. What you like to do on the battlefield.
2. What your weapons are made from.
3. Where you plan on going with your character classwise (ie staying fighter, going scout, going templar/adept).
My fighter presently has OHE and style master. I've used both longsword/shortsword, shortsword/spear, shortsword/shortsword, dagger/dagger and Longsword/Shield. My fighting styles however are VASTLY different however depending on the situation.
1) If I'm going frontline or teaming with another shield buddy, and am essentially 'tanking', I'll go longsword and shield. Being a lefty gives me the advantage of mirroring my buddy 9 times out of 10, as well as giving us a nice shield scover for a healer to hide behind or shoot arrows over. To me (with some exceptions) this is the 'less mobile style' where i will often pull this if i know I'm not going to be chasing after a lot of things, and am going to be a slower moving target for most of the fight. I also have to be aware of what packets are being thrown at me. At the same time, my shield is also made rather light, and the handle grip makes it easy to get it out of the way of spells (its the 'pointing down' grip, as opposed to the cross grip).
My normal tactic is usually Short sword and spear, because its rare that I'm a front-liner. The character I play is essentially a fighter who fights like a rogue, and usually fights with a rogue or adept buddy. Short sword and spear makes this easier for me, because, at least for me, they are more mobile type of weapons and are easier to run with (pumping arms to get speed with a shield on can sometimes be taxing for smallish people). Spear is exponentially more defensive than longsword, and for me is easy to use given my size (I'm 5'4" on a good day.). So long as you're careful about protecting your chest from the 'point of shame', you're usually good to go regarding defense with a spear. The one thing you lose in this combo however, is the reach of a long sword, unless you are of the school of Toepoking. Which I am.
Longsword shortsword was only used early on, and was double offense. You have to really, really know what you're doing with this style to make it effective. I couldn't, hence the switch to shortsword and spear.
Shortsword/Shortsword I now mainly reserve for claws, which is where dagger/dagger came from. Usually this was in times of emergency, and I usually make sure to have an alchemy buddy coat them with vorp serious coatings. This is also an incredibly hard style and should really be reserved for more knowledgable/advanced combatants, or the more mainly opportunistic fighting, as you lose an exponential amount of reach.
My scholar uses a bow, and my rogue will end up being shortsword and bow.
As far as 2H weapons (polearm, 2H sword, or otherwise), I don't usually use them, so I don't really have much to say regarding them, except I have seen them used with scary proficiency (ask any one about a character named Lupiticus sometime
)
2) Depending on what your materials are for your weapons also helps. if your shield is heavy, this adds to the 'not moving quickly' variable, as opposed to UL shields or weapons. So taking into account the maneuverability of your weaponry is also a big thing.
3) Depending on your eventual class (yay fluid classes!) is another thing to consider. I know a lot of templars who usually go for sword and shield - this allows you to put scrolls on the back of shields, or place potions on the back or other things that are handy for you. I know adepts who mainly go shortsword and spear because it allows for them to stay pretty mobile to get behind someone , and then packet the crap out of them when they turn around.
Fighters on the other hand come in all shapes and sizes..and scouts often choose weapon master/style master so that they can choose to be mobile or not mobile as the case may be.
Again, all of these are just suggestions, and there are exceptions to every rule, but these are my experiences regarding combat in the game. My best advice would be, in the offseason, get a bunch of people together and try them all out, and see which one you take to the easiest. Then, start with that one.
Hope this helps,
Ali
