An alternative to Thief.
Well here is the thing I love what you have purposed here.
BUT
Your out look on a thief is only but one. From reading your post and seeing some of the names you have throwing around
(Swashbuckler, Blade Dancer) I am betting your a D&D player, I may be worng but this is the premise I am working off here.
Even in D&D there are stealthy rouges or thieves, then there are up in your face rouges and thieves, then there is the Political and social thieve that does no fighting and destroys his enemies from a political point.
Like I said I like it ( what you posted ) just keep in mind there are many variations of Thieves/ Rouges and Arena net happen to choose the stealthy ones
Haha, I’ve never touched DnD. :P I just imagine that as the kind of person I would have fun playing as. Used some fancy other names to describe it. xD
The melee Ranger is currently pretty much what you want.
Sword especially has what you’re looking for with the autoattack being a swipe-kick-leap chain.
Even the greatsword has an attack+attack+evasiveattack chain.
(2) and (4) are Ranger sword (2) which is an attack huge leap backwards and a huge leap forwards+attack+cripple. All while evading due to agility and not stealthmagic.
(3) is Ranger sword (3) which is an agile leap behind the enemy. Poison is involved. All while evading due to agility again.
(4) is also Ranger Dagger (4) which is an attack+poison+evade.
Ranger also has a utility skill Lightning Reflexes where you dodge backwards and dead damage.
(5) is essentially the Warrior Sword (4) where you impale your enemy for bleeding on hit, and can use (4) again to rip the sword out for extra damage.
Yup add 2 additional jump/tumble utility skills to the melee ranger and you would have something good there. (ranger utility skills are pretty bland anyway)
Maybe add it as an alternative primary, I hear there a number of rangers that would prefer not to have their pet on the field and as a swashbuckler any pet that is not a hilarious enemy taunting parrot is not a good pet.
