build based on weapon boosts?
You’re always going to be giving up something for a 20% cooldown trait.
They can be good. They aren’t necessarily necessary. Good weapon swaps and skill use discipline will take you far.
They are only necessary if you don’t take 5 in Illusions, IMO. Beyond that, it depends.
I have both the Sword and the GS traits, but mostly because I love the -20% on the AE Knockback (handy in WvW) and because the Sword is quite multifunctional. Since I DW Swords and like the Spear underwater, a highly efficient trait.
The strength of heart to face oneself has been made manifest. The persona Carighan has appeared.
