The problem with "Instant OFF GCD" abilities makes combat feel less rewarding.

[Erudain]

it's the very long a$$ animations for skills previously casted.

i apologize for bring AION up, but back in AION that was the reason even casters went for "attack speed" weapons. a cleric would raise her hand and put it down after casting a heal. the "attack speed" weapon would make that movement faster. with semi-endgame weapon & glove, it made the movements very snappy. hands were raised, swinged and put down immediately after each skill.

Not to mention that as a melee dps you could weave/aac your auto-attcak to increase your dps...I'm not being able to do it here, since the auto-atk animation cannot be cancelled, if you auto-atk you have to watch your auto-atk
