I honestly don't know why they nerfed the PI because it was never a problem for me in PvP [Mythoclast did bother me, but only when there was two of them on the enemy team, but the PvE part should be treated separately]. But, I don't think raising the damage another hundred would change anything because the max level is 30 for anything. Have you seen a level 32 enemy? No? Then 300 Max is perfect because if you divide 300 by 10 you get 30 which means that a damage of 300 will use max base attack damage on level 30 enemies and lower. Get what I'm saying, or do you need more clarifying?
