I have spent a lot of time playing as the elf. The damage output of the daggers is great and the single target damge is amazing but they have their short comings in other categories. The light attack lack Cleve so their ability to clear hordes that are surrounding you Is pretty weak ( compared to duel swords, or spear for example ) small block angle requires quicker reactions to catch multiple strikes with a block with out getting staggered. And they lack reach. They are not nearly as versatile as many of the elf’s other weapons and I don’t believe any where near as survivable if your the last man standing.
I’d take the spear over the daggers if my group needs a tank or better special control, it’s ability to sweep and damage with a push strike is great. It’s also fantastic at stabbing a elite, special, berserker or boss while being out of range of a counter attack is super useful. And with the correct attack patterns it can make pretty short work of armor. It’s also super easy to push stuff off ledges with it.
Duel long swords are amazing for crowd control, stack Crit chance and Crit power and watch your flurry of light attacks take the heads off and stagger armored targets. And the stabbing block attack will drop bigger stuff with well placed shots to the head while only leaving your guard open for a brief moment.
Sword and dagger combo is the best of both the long swords and daggers once you master attack combos based on you current targets.
Single long sword is crazy useful, with a large mix of different possible attack patterns and a power attack the melts armored targets as well as a anti armor lunging stab it’s great for both tanking as well as more rogue like game play. As well as a good option for the waystalker if you find yourself constantly using your bow and your teammates are not watching your back while your dump arrows.
These are a few reasons why I don’t always take daggers as the elf.
