the crit chance was nerfed not the damage, and most still use those weapons cause its too hard to make a +12 , and since that's the weapon they added +12 +15 they just stick with it. Also , the other alternative for crit would be more damage or atributes, but they dont increase the damage that much , so even with the crit not that commom it is still a good thing to invest.
so u say its better to buy (now) a %crit sword as a P atck +41 sword ? if i got the money and the stones? or should i just keep getting the crit weapons and upgrade it to +12-14
Exactly, your critical rate ''depends'' of the target. At normal mobs i could say i critical 1 time each 2 hits (actually, sometimes you critical hit 3~4 times in a row). But you will rarely critical when PvPing or fighting a Boss. Another bad thing is that most of nameks/majins wear 18% anti crit chip x2~3 on their scouter.
But I still wear critical percentage. Really, 80 extra attack(you can get that bonus by upgrading your weapon by like 2 more times) on your weapons wouldn't make that difference anyway. And at grinding it's just awesome. Not to mention that if you critical at PvP (if you are lucky ofc) it's kinda a won match since you will hit 8k+ on a SK for example.
