There will always be people complaining, or in your vocabulary "QQ". That's just how the internet is. If the tomes are for EVERY class then why not. It adds more content so people don't get bored. It's not a PvP imbalance if everyone has it. If you don't want to take the time to farm it, then you're at a disadvantage.
I may add them, but it's up to you if you want more farming and more OP items and bigger PvP imbalance, cause this is what adding them would mean.
More people would be instant, with the tome i dont care if its here or not.
For reference, the tomes are (if I'm not mistaken.) :Dominance:Strength +25Dexterity +25Magic +25Critical Hit Rate +2%Channel -3%Interval Between Hits -0.05 secondSpeed +0.1 M/sHP +280Emperor:Strength +45Dexterity +45Magic +45Critical Hit Rate +3%Channel -5%Interval Between Hits -0.05 secondSpeed +0.2 M/sHP +400
