[PVE] When I can't stand still
If you’re using GS/Axe+Mace, you should have plenty of movement skills to keep up with the mobs. Just save your GS3/GS5 when you need close gaps.
Keep your rotations on stationary targets basic (GS2 + Burst), so that you can save your other weapon skills’ cooldowns for movement. When someone moves, use GS4 for extra ranged damage, then GS3/GS5 as necessary, or swap to Axe and Burst if you need a leap and you have the adrenaline.
Headbutt is another great skill for many reasons, including the movement feature. Use it liberally. The stun can stop mobs dead in their tracks. You should be able to keep up very high dps even with mobs that move around. GS burst on in Berserk mode (Arc Divider) has such a long range and high damage that you should be able to cut through open world mobs like butter.
