Tranquil doesnt last longer with rank, which is a pity.
Sorry, no vigilance on my build because I dont intend to do a lot of PvP. Melee scouts suck in that field a lot unfortunately. However, YOU will need it if your gonna PvP. Dont forget the anti+poisonous powder, its an awesome combo vs mage's reflections + it does some decent damage.(and is the only aoe we get
IMO, a 2yrd increase is hardly worth 5 skill points. However, if you think you can spare those points then go ahead man.
Stalker built scouts are actually superior to snipers in PvE, Cornered effect.
A Stalker can raise the DPS of the melee DPS in the group by a rather large percentage.
Look at it this way:
A typical melee-DPS will have his hits...
Parried(-50% dmg), Blocked(-75% dmg) or Dodged(-100% dmg) about 50% of the time(all of those in sum ofc) So...if you remove the mob's ability to Parry/Block/Dodge...their dps is gonna go waaaay up.
This also benefits the tank who now doesnt have to worry about missing a hit and loosing agro.
Besides, Kanian girls with dual swords looks [I Have a Potty Mouth] awesome!!!
