While this bug was caught during testing and did not make it into the game, the result of it being fixed meant that monster damage -- specifically damage done by monster abilities -- was ultimately higher at MP1 through MP10 than we intended it to be when 1.0.5 released.
I must be an idiot for not understanding how they can pick up a damage bug in testing, which they fixed before patch launch, yet still can cause the damage to be higher.
You are not an idiot. The ppl who fall for this cheap excuse are.
There was 1 month of PTR, yet they found this 'BUG' 5 days after it went live.
