Choose your weapon(s)

choose your weapon(s)

specifics:
you have 2 hands, and neither is big enough to wield a 2-hander by itself
speed is measured in seconds, lower is faster
there is no offhand damage penalty
armor reduces damage taken by a percentage, rather than a flat amount
blocking reduces damage taken by 90% after armor and only happens sometimes
all weapon-using abilities also hit with the offhand(if applicable) with whatever damage multiplier the main hand gets(if any) whenever it hits with the main hand
there are no exclusively two-handed or dual-wielding or one-handed or dagger weapon abilities, for the sake of simplicity
all weapon-using abilities' cooldowns are multiplied by(main hand weapon speed+offhand weapon speed)
all weapon-using abilities are on their own "global" cooldown separate from that of other abilities, and that weapon ability "global" cooldown is also multiplied by (main hand weapon speed+offhand weapon speed)

the amount of armor had by the enemies you'd be fighting can vary wildly between enemies as some may be cloth-wearing mages and some may be warriors in full plate armor with a shield, but no enemy is going to exceed 75% damage reduction from armor; no further information of that sort will be given

except that you dont know how many enemies are going to be wearing full plate with a shield(or lesser armor) and you dont know how many are just going to wear cloth(or more armor)

Two handing the 100-150 weapon does the most DPS on average of all of them.
(considering that 1.4 speed = 1.4 attack per 1.4second, 4 speed = 1 attack per 4 seconds)

I choose to switch all of them on the fly for crazy combos

The magic sword is OBVIOUSLY the best choice

It ignores armour and does a fair a mount of damage, so the damage will always be consistent

I would pick the big sword IF the damage gap was way smaller, that damage gap is just too hard to make it worthwhile, ergo making it the worst out of the bunch

The magic one.

I choose the third sword because I like traditional one handed swords

The choice between different swords would matter if the armor system reduced damage by a flat amount rather than a percentage. As it is now, all the weapons are the same except for the magic sword which is superior.

but you don't know how much arcane resistance the opponents have

but not many enemies are gonna have arcane resistance
