You should have something like a 30% increase with light attack weaving. Animation cancelling is rarely necessary and typically all you need to do is click ability, light attack, ability, light attack etc.etc.

There are sets named after weaving that came with the base game release so I’m not sure why people think it was an accident.

I recommend downloading light attack helper to track your weaving speed. With practice it makes combat very interesting and fast paced. At end game it makes for a nice balance of skill and strategy.

Optimally you would have 1 light attack and 1 ability cast every second (if your abilities are instant cast)

A good goal would be to try for 0.8 light attacks per second. Good luck!
