This^ for example, when I am doing abyssal demons for invention or slayer I bind cycle forward to 1 and the basic ability slice which is a 3 second (melee) cool down I have bound to my 2 key.
Revolution has kinks, which is why it is recommended to cancel abilities like flurry early. Same thing happens after you kill a monster, the game waits for another monster to attack you, then slow ass auto retaliate kicks in.
Binding 1 to cycle forward and 2 to slice let’s you skip the delay between auto retaliate. Just watch the monsters health bar and when it hits 0, hit your cycle forward then slice (or any other 3 sec cool down ability).
It’s AFK so don’t worry about it all the time, just do it when you’re eyes are actively on the screen.
