The PC Specific Guide by TheDuriel discusses ranged attack cancelling, however the same can be said for melee attack cancelling also, this is especially helpful on fights like Balrog and Nazgul as you can hit lightning, cancel animation and spam attack/cancel with Gandalf to get 4-5 attacks on Balrog before the next cycle, and with Nazgul you can spam attack/cancel as Aragorn and get him up in the air in less than 10 seconds of fight starting if done right. Will be uploading my run shortly which highlights both of these tricks, and they are also used in other areas of the run for trash mobs.
