Guild Wars 2

So, I’m trying to find what to switch from signet warrior to.

At lower levels, the +precision from the trait in the arms line is pretty OP, but at later levels i’m assuming it’s not as great to be using….so what is the preferred build to switch to as a heavy power/precision build with a greatsword?

Full Berserker with Greatsword. I personally always run signet of rage.

Your utilites range from the PvE instance:
A general pug run with 0 other warriors – Run Shake It Off, FGJ, optional
COF P1 Farm – OMM, FGJ, Banner

For Great Justice and Signet of Rage always, they never leave my skillbar. I always go Banner of Discipline because +10% crit damage and about +4% crit chance to the whole party is great (healing too if traited.) Note that banner effects don’t stack, so sort that out so there’s only one of each type if you’ve got multiple warriors. Though to be honest BoD is the only one worth having. The 3rd one changes between each encounter, from OMM if I’m expecting little resistance, Fear Me/Endure Pain for running, Balanced Stance if I know there’s a lot of CC involved. Though its usually Signet of Stamina for the condition wipe and endurance regen increase, which is better than Shake it Off IMO.

As far as armour goes, any combination of PVT/Knights/Berserkers that can give you enough precision for regular critical hits. I think I sit at about 50% crit chance outside of combat, but I’ve got +9% from discipline trait, +5% sigil, +20% constant fury, +Banner of Discipline, +Food Buffs, +Utility if you’re made of money. Then it’s just a matter of tweaking towards Crit Damage or defensive stats to suit your play style, as Power is in all 3 sets (only a secondary in Knights, it’s why I’ll never go near that garbage.)

Yeah getting the extra precision as soon as possible is OP.
Later on you want to play For Great Justice, anything else is up to you but the trusty Shake it off is versatile and will help you countless times.

FGJ / Shake it off / Banner x1 / Signet of Rage is my dungeon set-up. For open world you don’t really need something else that your skill 1.
