Best wep combo PVE?
You have two weaponslots, 5 seconds weaponswap recharge and much space in you inventory – use it wisely.
Usually GS + Axe/Mace, and every weapon used by a warrior in the bag.
If you play open PvE (exporing n stuff) use GS + Sword/Warhorn. GS does enough dmg and the mobility is insane.
