Blood Hunt many bugs

1.Why Blood Hunt can't gain Combo to Culmination?
2.Why Blood Hunt can't lunge at target on first attack while lunges at target on second attack with key always pressing and target not moved?
3.Blood Hunt can't find enemy in 1 meter standing on two side of actor. Because the angle of mouse, actor and enemy is 90 degree. This is so awful.
4. Trimmed Greaves cause gained cold damage to freeze enemy but Elemental Invocation can't gain energy from that freeze. The other two elemental damage can't gain energy too.

I see why Elemental Invocation can't gain energy. The freeze must caused by skill.

4. Why Blood Hunt sometimes dragging? One frame the character dashes into the monster, but the next frame they are dragged back to the original position. If the skill is held down, this dragging repeats continuously. This is likely caused by inconsistent calculations between the server and client, perhaps due to poor synchronization of configuration settings.
