The Rapid Strike technique, as found on a number of weapons and some martial arts styles, halves the time cost of an attack. That’s… really strong. Effectively doubles your DPS and it triggers every attack.
This also leads to odd situations where you don’t want other techniques available, because then they can trigger instead of Rapid Strike. Karate for example, when you get your skill up you gain Precise Strike which triggers on crits meaning you’ve gone from effectively-double-damage to no-bonus-damage on many attacks. Or when you upgrade your katana to a diamond katana - again Precise Strike is added, meaning your attack rate slows right down.
I think Rapid Strike is currently far too good, and should be nerfed down to where it’s comparable to other techniques. Rather than halving the time cost of an attack, how about reducing it by 25%? Or only trigger sometimes?
