I’d really like to see daggers made available as a main-hand weapon for Rangers, but as a ranged weapon similar to how the Ranger uses axes. I personally love throwing daggers, and no one has that option aside from a single off-hand skill here or there. It would fit the Ranger theme perfectly to have throwing daggers, and shouldn’t be that difficult since it would require only 3 new skills.
Axes are also currently the only ranged main-hand option we have compared to 4 different off-hands. Hell, Rangers only have two main-hand options total.
To top it all off, the Thief is currently the only class that really -uses- daggers at all. The Necromancer and Elementalist can equip daggers, but they pretty much just cast spells while holding them. All but the Necro auto-attack don’t even really appear to at the very least cast -with- the dagger.
