The critical stat is the worst stat in the game and should receive a buff. If you want to go for pure defense you use HP and DEF stat boosts/buffs which work well for teams who want high sustain. If you want to go for pure offense then you use ATK and CRIT stat boosts/buffs. Sadly, you need to invest “too many” points into CRIT for it to proc often while defense is a constant factor when dealing/taking damage. They’re are a few other disadvantages of using CRIT over DEF and/or HP.
My suggestion is that we remove the critical stat and add the stat, precision. What is precision? Precision, is a stat that boosts the odds of applying weapon abilities like stun when attacking, bleeding when attacking, etc. Not only that but it also reduces the odds(slightly) of getting stunned, impaired etc. when you attack so that you can attack those stingy defensive teams without being punished harshly for using your basic attacks. Precision would also have all the functions of the old CRIT stat.
I believe we’d see a lot more uniqueness in the weapons people craft. Imagine being able to leech health with a higher success rate or being able to attack a team on defense with raw damage without the fear of losing out on significant damage.
