Sacred Haven of Debauchery

I took a Warrior to attack with an auto-attack, or, God forbid, to use a skill, I have to run up close to the mob and turn to face it, and only then can I attack. What's the point of the mouse in this situation?

How else should it be? Should it be like in Lineage, where arrows and spells fly through three floors? True, that's how it looks in PvE – a mage or hunter kiting a melee unit, while two melee units dance and jump. On the other hand, that's the only way I PvPed.
