I don’t know why WW mastery is called combo strike, it is anything but. You just use your abilities on CD (FoF,SRK), then your fillers in sequence. If you try anything else (like squeeze in BoKs to reduce SRK CD) you get punished with reduced damage, super boring and nothing like in fighting games at all…
Some idea how it should work: without taking break for 1.5 sec (movement, cc, defensive abilities) offensive abilities keep increasing damage. Mastery would increase damage increase speed and cap.
