Ya know, I think a cool idea could be to have new weapon types with other attribute requirements.
I've seen an old thread on Rangers wanting a Beast Mastery weapon (like a whip or whatever), and this thread just got me reminded of that. What if there were new weapons for all the characters that could have unique attack styles/damage/damage-types?
Some examples of what I mean: (aside from the Ranger Beast Mastery Whip)
Necromancer [Blood Magic] Claws
2-handed, Melee, stats equivalent to a staff (mods, upgrades and everything)
Mesmer [Domination] Rapier/Cane Sword
1-handed, Melee, standard wand style (no upgrades, just inherent mods)
Monk [Smiting] Bo-Staff (similar to the existing Bo-Staff)
2-handed, Melee, normal staff stats
In essence, the weapon simply replaces their normal staff or wand, and instead of ranged, it's melee, possibly for a little bit more damage and/or faster speed. There could be weapon attacks tied into those attributes (I could see a Mesmer making someone "Beg for Mercy" using his Rapier), or they could just use it as a secondary form of damage as the staves/wands are now.
I just think this could add a sense of style!
